Prep the chickpeas. Drain and rinse the chickpeas in a colander. Pat them very dry with a clean kitchen towel or paper towels. Removing as much moisture as possible helps them get really crispy.
Season the chickpeas. Add the chickpeas to a mixing bowl. Toss with olive oil, paprika, garlic powder, oregano, salt and black pepper until every chickpea is coated in the seasoning.
Cook the chickpeas in the air fryer or oven. For the air fryer: preheat to 390°F (200°C). Add the chickpeas in a single layer in the basket and cook for 10 to 12 minutes, shaking the basket halfway through, until they are golden and crispy.For the oven: preheat to 425°F (220°C). Spread the chickpeas on a parchment lined baking sheet and roast for 18 to 20 minutes, stirring once, until crisp.
Prepare the bowl base. While the chickpeas cook, warm the cooked quinoa if needed. Place a layer of fresh spinach at the bottom of each bowl. Add quinoa on top of the spinach, dividing it between the two bowls.
Add the fresh veggies. Slice the cherry tomatoes in halves and dice the cucumber. Arrange the tomatoes and cucumber in small sections around the quinoa. This makes the bowl colorful and easy to style.
Make the tahini sauce. In a small bowl, whisk together tahini, lemon juice, maple syrup, grated garlic and a pinch of salt. Add water one tablespoon at a time, whisking until the sauce becomes smooth and pourable. It should be creamy, not too thick and not too runny.
Assemble the power bowls. Top each bowl with a generous handful of crispy chickpeas. Drizzle the tahini sauce over the top. Add extra salt, pepper or lemon to taste if needed.
Serve. Serve the bowls right away while the chickpeas are still warm and crispy. Enjoy as a quick high-protein lunch or a colorful weeknight dinner.
