01 - Set the oven to 425°F to reach roasting temperature.
02 - In a large bowl, toss together the zucchini, red and yellow bell peppers, red onion, eggplant, cherry tomatoes, and chickpeas.
03 - Drizzle olive oil over the vegetables and chickpeas, then add dried oregano, dried thyme, smoked paprika, salt, and black pepper. Toss until everything is evenly coated.
04 - Spread the seasoned mixture across a large parchment-lined baking sheet in a single, even layer.
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, ground cumin, and salt in a small bowl until smooth and creamy. Thin with additional water if a lighter consistency is preferred.
07 - Divide the cooked quinoa or brown rice among four serving bowls.
08 - Spoon the roasted vegetable and chickpea mixture over the grain base, then drizzle generously with the tahini-lemon dressing.
09 - Finish each bowl with chopped fresh parsley, kalamata olives, and a lemon wedge. Serve warm.
