01 - Set the oven to 425°F and allow it to reach full temperature before roasting.
02 - Place zucchini, red and yellow bell peppers, red onion, eggplant, cherry tomatoes, and chickpeas in a large mixing bowl.
03 - Drizzle olive oil over the vegetables and chickpeas. Add oregano, thyme, smoked paprika, salt, and pepper, then toss until everything is evenly coated.
04 - Spread the seasoned mixture across a parchment-lined baking sheet in a single, even layer to promote proper caramelization.
05 - Roast for 25 to 30 minutes, stirring once at the halfway mark, until the vegetables are golden-edged and tender.
06 - While the vegetables roast, whisk together tahini, lemon juice, water, minced garlic, cumin, and salt in a small bowl until smooth and creamy. Add more water if a thinner consistency is preferred.
07 - Divide cooked quinoa or brown rice among 4 serving bowls, then top with the roasted vegetable and chickpea mixture.
08 - Drizzle tahini-lemon dressing generously over each bowl. Finish with chopped fresh parsley, kalamata olives, and lemon wedges. Serve warm.
