Greek Mezze Salad

Preheat oven to 450 degrees. On a rimmed baking sheet, toss chickpeas with 6 tablespoons oil and za'atar. Season with kosher salt and pepper. Roast 15 minutes. Add pitas to sheet, stir to coat, and roast until chickpeas and pitas are crisp, about 10 minutes more.

Meanwhile, stir together yogurt and zest; season with salt and pepper. In a bowl, toss together radishes, cucumbers, lemon juice, and remaining 2 tablespoons oil. Season with kosher salt and pepper. Just before serving, dollop plates with yogurt mixture; top each with cucumber salad, chickpea mixture, and 2 grape leaves. Garnish with mint, more za'atar, and drizzles of oil; serve.
