Place the bell peppers, cucumbers, tomatoes, red onions, mint and parsley in a large bowl. In a separate bowl combine the garlic with the olive oil and lemon juice. Season to taste with salt and freshly ground black pepper. Pour the dressing over the salad and toss lightly to mix. Toast the pita breads in a toaster until crisp and serve along side or crumbled on top of salad. Serves 4.
