01 - Preheat oven to 425°F. Line two baking sheets with parchment paper to prevent sticking and ensure easy cleanup.
02 - Pat chickpeas thoroughly dry with a clean kitchen towel to ensure crispiness. Toss with olive oil, smoked paprika, cumin, garlic powder, salt, and pepper until evenly coated. Spread seasoned chickpeas on half of one baking sheet in a single layer.
03 - Arrange diced sweet potato, bell pepper, zucchini slices, and red onion on the second baking sheet. Drizzle with olive oil, then sprinkle with oregano, salt, and pepper. Toss vegetables with hands or utensils to coat evenly, then spread in a single layer.
04 - Place both baking sheets in the preheated oven. Roast for 25–30 minutes, stirring chickpeas and vegetables once halfway through cooking time. Chickpeas should be crispy and vegetables tender with lightly browned edges.
05 - While vegetables roast, combine rinsed quinoa, water or broth, and salt in a saucepan. Bring to a boil over high heat, then reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Fluff quinoa gently with a fork before serving.
06 - Whisk together tahini, lemon juice, water, maple syrup, grated garlic, salt, and pepper in a small bowl until completely smooth. Add additional water, 1 teaspoon at a time, if needed to achieve pourable consistency.
07 - Divide cooked quinoa among four bowls. Arrange roasted vegetables, crispy chickpeas, fresh spinach or greens, and pumpkin seeds on top of each bowl. Drizzle with tahini dressing and garnish with chopped fresh herbs if desired. Serve immediately while chickpeas remain crisp.
