Lebanese Fattoush Salad with Grilled Chicken

To prepare salad: Preheat oven to 350F. Place pita halves rough-side up on a large baking sheet. Brush with 1 tablespoon oil and sprinkle with 1 teaspoon sumac. Bake until golden and crisp, about 15 minutes. When cool, break into bite-size pieces.

Whisk lemon juice, salt, pepper and the remaining 2 tablespoons oil and 1/4 teaspoon sumac in a large bowl. Add lettuce, tomatoes, cucumber, onion, mint and the pita pieces; toss to coat. Let stand for 15 minutes.

To prepare chicken: Meanwhile, preheat grill to medium-high. Rub the chicken with oil and season with salt and pepper. Grill until no longer pink inside, 3 to 4 minutes per side. (Alternatively, broil chicken 4 to 6 inches from the heat source for about 6 minutes per side.) Slice the chicken thinly and serve on top of the salad.
