01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper for easy cleanup.
02 - In a large bowl, combine the diced sweet potatoes and sliced red onion with 1 tablespoon olive oil. Add half the smoked paprika, cumin, coriander, salt, and pepper. Toss until evenly coated.
03 - Pat the chickpeas thoroughly dry with paper towels to ensure crispiness. Toss with the remaining olive oil, paprika, cumin, coriander, salt, and pepper until well coated.
04 - Spread the vegetables on one side of the prepared baking sheet and the chickpeas on the other side. Roast for 25 to 30 minutes, stirring halfway through cooking, until the sweet potatoes are tender and the chickpeas are golden and crispy.
05 - While the vegetables roast, whisk together the tahini, lemon juice, maple syrup, water, minced garlic, and salt in a small bowl. Add additional water as needed to achieve a smooth, pourable consistency.
06 - Divide the baby spinach or mixed greens evenly among 4 bowls. Top each bowl with the roasted sweet potatoes, crispy chickpeas, roasted red onion, and sliced avocado.
07 - Drizzle the tahini dressing generously over each bowl. Sprinkle with pumpkin seeds or sunflower seeds and fresh herbs if using. Serve immediately while the roasted components are still warm.
