Step 1Heat the oven to 425 degrees. In a large bowl, combine the yogurt, 1/3 cup olive oil, vinegar, garlic, sumac, 1 tablespoon Aleppo pepper and lemon juice. Add tomatoes, cucumbers and radishes, toss and set aside.
Step 2Place the torn pita bread and garbanzo beans on a rimmed baking sheet and toss with the remaining oil, Aleppo pepper and salt. Bake until crisp and golden, about 15 minutes. Remove and set aside to cool.
Step 3Add the parsley, mint and greens to the bowl and toss in the cooled pitas. Serve immediately.
