Roasted Sweet Potato, Chickpea & Arugula Power Bowl
My Favourite Autumnal Vegan Meal
I think I may have found my favourite autumnal meal, and quite possibly your new favourite, too.
This Roasted Sweet Potato, Chickpea & Arugula Power Bowl is absolutely gorgeous. It’s one of those meals that feels abundant the moment you put it on the table: golden roasted sweet potatoes, crispy spiced chickpeas, peppery arugula, fluffy quinoa, creamy avocado, crunchy walnuts and little jewels of pomegranate, all brought together with the most delicious lemon-tahini dressing.
It tastes like autumn in a bowl.
There’s warmth and sweetness from the roasted potato, freshness from the greens, a little sharpness from the pomegranate and lemon, and that beautiful combination of creamy and crunchy that makes every bite slightly different. It feels wholesome and comforting without being heavy, exactly the sort of food I find myself craving as the days begin to soften into autumn. And beneath all that beauty, it is an incredibly nourishing whole-food plant-based vegan meal.
Chickpeas and quinoa make it substantial enough for a proper lunch or dinner, while walnuts, tahini and avocado bring richness without needing a heavy processed sauce. Then there are all those wonderful plants, leafy greens, sweet potato, pomegranate, sesame, walnuts, legumes and quinoa, each bringing something slightly different to the table.
Perhaps my favourite thing about it, though, is that it doesn't feel like a meal designed around nutrition. It simply feels like beautiful food.
The sort of bowl I want to make on a quiet September afternoon, when the windows are open just enough to let the cooler air in, something warm is roasting in the oven and autumn is beginning to make itself known.
It has very quickly become a favourite in my kitchen, and I have a feeling it might become one in yours too.

Roasted Sweet Potato, Chickpea & Arugula Power Bowl
Serves: 2 generous portions Prep time: 15 minutes Cooking time: 30–35 minutes Total time: approximately 45 minutes
You'll Need
For the bowl
1 cup cooked quinoa
1 cup cooked chickpeas, drained and rinsed
1 large sweet potato, approximately 300 g
4 generous cups fresh arugula
1 medium avocado
¼ cup raw walnuts, roughly chopped
¼ cup fresh pomegranate arils OR dried cranberries
fresh lemon, to finish
For the roasted sweet potato
1 tsp smoked paprika
½ tsp garlic powder
½ tsp ground cumin
freshly ground black pepper
chili flakes, optional
small pinch of sea salt, optional
For the crispy chickpeas
½ tsp smoked paprika
½ tsp garlic powder
¼ tsp cumin
freshly ground black pepper
For the Lemon-Tahini Dressing
2 tbsp tahini
2 tbsp fresh lemon juice
1 small garlic clove, finely grated
2–4 tbsp warm water
freshly ground black pepper
½ tsp Dijon mustard, optional
½–1 tsp date syrup, optional
How to Make It
1. Begin With the Quinoa
Rinse your quinoa thoroughly under cool running water.
For this recipe, cook approximately ½ cup dry quinoa according to the packet instructions. A useful starting ratio is around one part quinoa to two parts water, although some varieties need slightly less.
Bring it to a boil, lower the heat, cover and simmer gently for around 15 minutes, or until the water has been absorbed.
Then do something surprisingly important:
Leave it alone.
Take the pan off the heat and allow the quinoa to sit, covered, for another five to ten minutes before fluffing it with a fork.
You get much lighter, fluffier grains this way rather than wet quinoa collapsing sadly at the bottom of your bowl.
2. Make Those Beautiful Golden Sweet Potatoes
Preheat your oven to 220°C / 425°F.
Cut the sweet potato into roughly 2 cm cubes. Keeping them reasonably similar in size helps everything roast evenly.
Add the paprika, garlic, cumin, black pepper and chili if you're using it.
For an oil-free whole-food plant-based version, add a tiny splash of water, lemon juice or aquafaba to help the spices cling to the potato.
Spread the cubes across a parchment-lined tray.
And give them room.
This is one of those tiny cooking details that makes an enormous difference. When vegetables are crowded together, the moisture they release gets trapped and they begin steaming one another. When they have space, their surfaces can dry and caramelise.
Roast for 25–35 minutes, turning them around halfway through.
You want deeply golden corners with beautifully soft, almost creamy centres.
Try not to eat half of them directly from the tray.
I make no promises.
3. Get the Chickpeas Properly Crispy
Drain and rinse the chickpeas, then dry them extremely well.
This matters.
Water is the enemy of crispness, and slightly damp chickpeas will simply sit in the oven contemplating their existence rather than becoming the crunchy little things we actually want.
Toss them with smoked paprika, garlic, cumin and black pepper.
Spread them across the tray and roast at 220°C / 425°F for approximately 25–35 minutes, giving them a shake halfway through.
For even more crunch, turn the oven off when they're finished and leave them inside for another five or ten minutes.
Watch them closely towards the end.
4. Make the Creamy Lemon-Tahini Dressing
This might be my favourite part.
Combine the tahini, fresh lemon juice and grated garlic in a little bowl.
Start whisking.
At first, the tahini will probably thicken dramatically and look as though you've done something terribly wrong.
You haven't.
Add warm water, one tablespoon at a time, and keep whisking. It will suddenly loosen into the palest, silkiest dressing.
Add black pepper and taste.
If you like a sharper dressing, add more lemon.
For something slightly sweeter, add a little date syrup.
For more depth, whisk in Dijon mustard.
I like mine very lemony, garlicky and just thin enough to fall beautifully from a spoon.
Assemble Your Bowl
Now comes the lovely part.
Start with a generous bed of fresh arugula.
Spoon over the fluffy quinoa, followed by those still-warm roasted sweet potatoes and crispy chickpeas.
Add sliced avocado.
Scatter walnuts generously across the top.
Then add the pomegranate or cranberries.
Please don't skip it unless you absolutely have to. Those little ruby-red jewels do much more than make the photograph pretty. Their tart freshness is wonderful against the sweet potato and rich tahini.
Drizzle over the lemon-tahini dressing.
Finish with freshly cracked black pepper and a squeeze of lemon.
And there she is.
Autumn in a bowl.
My Favourite Seasoning Combination
If you're making this for the first time, I would begin with:
Smoked paprika + cumin + garlic + black pepper + chili + lemon.
There's enough warmth to make the roasted ingredients feel wonderfully autumnal, but nothing overwhelms the freshness of the arugula and pomegranate.
Once you've made the original, though, this bowl is very easy to reinvent.
Mediterranean
Use oregano, thyme, rosemary, garlic, black pepper and lemon zest.
Add fresh parsley or mint at the end.
Middle Eastern
Try cumin, coriander, sumac and paprika.
Finish with fresh mint, parsley and plenty of pomegranate.
Za'atar is wonderful here too.
Moroccan-Inspired
Season with cumin, coriander, turmeric, ginger, paprika and the tiniest touch of cinnamon.
The warmth of the spices with sweet potato is extraordinary.
Smoky & Spicy
Use smoked paprika, chipotle, cumin, garlic and cayenne.
Swap some of the lemon for fresh lime.
Herby Autumn
Use rosemary, thyme, sage, garlic and black pepper.
This version is especially lovely when the weather properly turns cold.
The Nutrition Behind This Bowl
This is where the recipe becomes particularly lovely.
Its nutritional value isn't dependent on one fashionable ingredient.
It comes from diversity.
Within one meal, you're getting legumes, leafy greens, orange vegetables, fruit, nuts, seeds and a nutrient-rich pseudocereal.
That means protein and complex carbohydrate sit alongside fiber, unsaturated fats, carotenoids, folate, potassium, magnesium, iron, copper, manganese and numerous phytochemicals.
Approximate Nutrition Per Serving
Based on two generous servings and half the tahini dressing per person:
Calories: approximately 650–700 kcal
Protein: approximately 19–21 g
Carbohydrates: approximately 80–85 g
Fiber: approximately 19–21 g
Fat: approximately 30–33 g
Saturated fat: approximately 4 g
Cholesterol: 0 mg
The bowl also provides meaningful amounts of:
vitamin A precursors
vitamin C
vitamin E
vitamin K
folate
vitamin B6
magnesium
potassium
iron
zinc
copper
manganese
phosphorus
The precise nutritional values will vary depending on ingredient varieties, weights and brands, so these figures should be treated as estimates.
Sweet Potato: That Colour Is Doing Something
I adore sweet potato anyway, but its deep orange colour gives us a clue to one of its nutritional strengths.
Orange-fleshed sweet potatoes are exceptionally rich in beta-carotene, which our bodies can convert into vitamin A.
Vitamin A contributes to normal vision, immune function and normal cellular processes.
Sweet potato also gives us fiber, potassium and other micronutrients.
And here's a lovely bit of food synergy: carotenoids are fat-soluble. Eating carotenoid-rich vegetables as part of a meal containing fat can improve their bioavailability.
Our sweet potato happens to be sitting beside avocado, walnuts and tahini.
Sometimes good nutrition is deliciously convenient.
Chickpeas: Humble Little Nutritional Powerhouses
I think chickpeas deserve far more glamour than we give them.
They're inexpensive, enormously versatile and bring together two things I particularly want from a substantial plant-based meal:
protein and fiber.
They also provide folate, iron, phosphorus, manganese and other micronutrients.
Legumes as a broader food group have been extensively studied in relation to cardiometabolic health. Controlled-trial evidence suggests that incorporating legumes can improve certain cardiovascular and metabolic risk markers, although the size and certainty of effects vary depending on the outcome and study.
That distinction is important.
No single chickpea is going to save your cardiovascular system.
A dietary pattern that regularly includes legumes, whole grains, vegetables, fruit, nuts and seeds is a far more scientifically sensible thing to celebrate.
Quinoa: Useful, Delicious and Slightly Misunderstood
Quinoa is often described as a grain, although botanically it is a pseudocereal.
It contains carbohydrate, fiber and protein alongside magnesium, phosphorus, manganese, folate and iron.
You'll often hear that quinoa is a "complete protein." That is technically useful information: it contains all nine essential amino acids.
It does not mean quinoa contains enormous quantities of protein.
I love it here because it gives the bowl substance, absorbs the dressing beautifully and works wonderfully beside chickpeas.
Walnuts & Plant-Based Omega-3
Walnuts are one of my favourite additions because a small amount completely changes the texture of the bowl.
They are also unusual among commonly consumed nuts for their relatively high content of alpha-linolenic acid (ALA), an essential omega-3 fatty acid.
Randomised controlled trial meta-analyses have found that walnut-containing diets can modestly reduce LDL cholesterol and total cholesterol compared with control diets.
Walnuts also provide protein, fiber, copper, manganese and polyphenols.
And perhaps most importantly for this recipe:
they crunch.
Nutrition and pleasure are allowed to exist in the same sentence.
Arugula: The Peppery Green I Never Tire Of
Arugula — or rocket, depending on where you live — belongs to the cruciferous vegetable family.
It contributes vitamin K, folate, carotenoids and various plant compounds, including glucosinolate-derived compounds characteristic of cruciferous vegetables.
But I use it here for another reason too.
Flavour.
Its slight bitterness and peppery edge cut through the sweetness of the potato and richness of the avocado and tahini.
Without the arugula, the bowl becomes softer and sweeter.
With it, everything wakes up.
Tahini Deserves Its Own Love Letter
Tahini is simply ground sesame seed, yet somehow lemon, garlic and water transform it into something that tastes infinitely more indulgent.
Sesame provides unsaturated fats, protein and minerals including copper, phosphorus and iron. Calcium content can vary considerably depending on how the tahini is produced and whether the sesame seeds are hulled.
Tahini is energy-dense, so you don't need enormous quantities.
Two tablespoons make plenty of dressing for this recipe.
Why Add Lemon?
Beyond flavour, lemon serves a useful nutritional purpose.
Plant foods such as chickpeas, quinoa, sesame and leafy greens contain non-heme iron.
Vitamin C consumed alongside plant sources of iron can increase non-heme iron absorption.
So that generous squeeze of lemon isn't merely there because I apparently believe everything in life improves with citrus.
Although I do.
What About the Pomegranate?
Pomegranate brings fiber, micronutrients and a range of polyphenolic compounds.
You'll see dramatic health claims made about pomegranate online, and this is where I prefer a little restraint.
I don't think we need to promise that a spoonful of pomegranate will "detoxify" anything or extinguish inflammation overnight.
It is a beautiful whole fruit.
It contributes useful nutrients and plant compounds.
And it makes this bowl taste absolutely wonderful.
That is more than enough.
Why Whole-Food Plant-Based?
The strongest thing about this recipe isn't any one so-called superfood.
It's the pattern.
This one bowl combines:
legumes + vegetables + leafy greens + whole plant carbohydrates + nuts + seeds + fruit.
That's exactly why I prefer thinking about nutrition through the lens of dietary patterns rather than miracle ingredients.
Research consistently supports dietary patterns rich in minimally processed plant foods, including vegetables, fruits, legumes, whole grains, nuts and seeds, in relation to cardiovascular and metabolic health.
That doesn't make every vegan food automatically healthy.
And it doesn't mean we need dietary perfection.
It simply gives us a remarkably good foundation on which to build.
Is This Bowl Completely Whole-Food Plant-Based?
It can be.
For the strictest WFPB version, use:
quinoa
chickpeas
sweet potato
arugula
avocado
walnuts
pomegranate
pure tahini
lemon
garlic
herbs and spices
Leave out added oil, refined sugar and heavily processed sauces.
If you avoid added salt, simply omit it.
I personally don't think beautiful whole-food cooking should feel like a punishment for having taste buds, so herbs, spices, citrus, garlic and contrasting textures become incredibly important.
Meal Prep
This is a wonderful meal to prepare ahead, although I wouldn't assemble everything on Sunday and expect Friday's arugula to remain a picture of youthful optimism.
Prepare the components instead.
Cook the quinoa.
Roast the sweet potatoes.
Cook or roast the chickpeas.
Make the dressing.
Wash and thoroughly dry the greens.
Then store everything separately in the refrigerator.
When you're ready to eat, warm the quinoa, chickpeas and potato if you like, then add them to fresh arugula with avocado, walnuts, pomegranate and dressing.
For food safety, cooked leftovers should be refrigerated promptly and generally used within 3–4 days.
The roasted chickpeas will soften in the refrigerator. A few minutes back in the oven or air fryer will bring some of their crunch back.
A Few Final Tips
Give the sweet potatoes room.We want roasting, not steaming.
Use fresh lemon.The brightness is essential here.
Don't dress the arugula too early.Add the tahini just before eating.
Taste as you go.If the bowl feels too rich, add lemon. Too sharp? Add more sweet potato or avocado. Too soft? More walnuts or chickpeas. Too sweet? More arugula and black pepper.
Good cooking is very often about balance rather than adding more ingredients.
Frequently Asked Questions (FAQ)
Is this vegan power bowl gluten-free?
Yes. Quinoa, chickpeas, sweet potato, arugula, avocado, walnuts, pomegranate and tahini are naturally gluten-free. If adding Dijon or packaged seasonings, check their labels if you need to avoid gluten for medical reasons.
Can I make it without oil?
Absolutely. The recipe can be completely oil-free. Use a splash of water, lemon juice or aquafaba to help your seasonings adhere before roasting.
Can I make this vegan bowl ahead of time?
Yes. Prepare the quinoa, chickpeas, sweet potato and tahini dressing in advance, but store the components separately and add avocado and dressing shortly before serving.
What can I substitute for quinoa?
Brown rice, buckwheat, barley, farro or another favourite whole grain can work. Choose buckwheat or brown rice if you need the finished meal to remain gluten-free.
What can I use instead of chickpeas?
Lentils, cannellini beans, black beans or edamame all work. Edamame is particularly useful if you want more protein.
Is this a high-protein vegan meal?
The standard recipe provides approximately 20 g protein per generous serving, depending on exact ingredient quantities. For higher protein requirements, increase the legumes and add edamame and hemp hearts.
Is this recipe suitable for autumn meal prep?
Very much so. Sweet potato, walnuts, warm spices and pomegranate make it particularly lovely for autumn, while the quinoa and chickpeas make it substantial enough for lunch or dinner.
My Favourite Autumn Bowl
There is something about this meal that captures precisely how I want to eat at this time of year.
The food is getting warmer, but I'm not quite ready for months of heavy stews.
I still want greens.
I still want freshness.
I want something colourful enough to make an ordinary weekday lunch feel rather lovely.
But I also want trays coming out of the oven, sweet potatoes with caramelised edges, warm spices, toasted walnuts and something creamy drizzled generously over the whole thing.
This bowl lives exactly there.
Between summer's freshness and autumn's comfort.
It's gorgeous enough to make for friends, practical enough for a weekday, nourishing enough to become part of your regular rotation and endlessly adaptable depending on whatever happens to be waiting in the vegetable drawer.
My favourite autumnal meal.
And perhaps, after one gloriously messy spoonful of crispy chickpeas, sweet potato, pomegranate and lemon tahini, your new favourite too.
