Wash and dry all produce. Preheat oven to 425 degrees. Slice olives crosswise. Slice cucumbers into thin rounds. Halve grape tomatoes lengthwise. Halve, peel, and thinly slice shallot. Thinly slice garlic. Pick parsley leaves from stems; discard stems. Drain and rinse chickpeas.

On a baking sheet, toss chickpeas, cumin, a drizzle of olive oil, and a pinch of salt and pepper. Bake in oven until crisp, about 20 minutes. (TIP: Chickpeas may pop in oven—it’s natural.) Set aside and let cool for a few minutes after removing from oven.

Heat 2 TBSP olive oil in a small pan over medium heat. Add garlic and cook until it just begins to brown, 1-2 minutes. Remove pan from heat. Using a slotted spoon, remove garlic from pan and discard.

Sprinkle pitas with a drizzle of olive oil, za’atar, salt, and pepper. Place on another baking sheet and toast in oven until crisp and toasty, 6-8 minutes. (TIP: You can add the pitas to the baking sheet with the chickpeas, if there’s room.) Remove from oven and let cool. Once cool enough to handle, cut into 1-inch squares. Place squares and cooled chickpeas in a large bowl.

Whisk vinegar into pan with garlic oil. Season with salt and pepper.

Add cucumber, olives, tomatoes, parsley, and as much shallot as you like to bowl with pitas and chickpeas. Drizzle with vinaigrette (to taste) and toss thoroughly to coat. (TIP: If salad seems dry, add more olive oil.) Season generously with salt and pepper. Divide between bowls, then sprinkle with feta.
