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