01 - Preheat oven to 425°F. Line two baking sheets with parchment paper.
02 - Pat chickpeas dry with a towel. Toss with olive oil, smoked paprika, cumin, garlic powder, salt, and pepper. Spread on half of one baking sheet.

04 - Roast chickpeas and veggies for 25-30 minutes, stirring once halfway, until chickpeas are crisp and vegetables are tender and lightly browned.

06 - Whisk together tahini, lemon juice, water, maple syrup, garlic, salt, and pepper until smooth. Add more water if needed for a pourable consistency.
07 - Divide quinoa among four bowls. Top with roasted veggies, chickpeas, spinach or greens, and pumpkin seeds. Drizzle with tahini dressing and garnish with fresh herbs if desired.
