Preheat the oven to 450°F.
On a large sheet pan, combine chickpeas, olives, cherry tomatoes, zucchini, feta, and red onions.
Drizzle with olive oil and lemon juice, then sprinkle with oregano, salt, and pepper. Toss until everything is evenly coated.
Spread the ingredients into a single layer.
Roast for 35–40 minutes, until the zucchini is tender, the tomatoes begin to burst, and the vegetables are lightly golden.
Serve warm, optionally garnished with fresh parsley or an extra squeeze of lemon.
