4 (2.75-ounce) Mediterranean-style wheat flatbreads (such as Toufayan)
1/2 cup vertically sliced red onion (about 1/2 small onion)
1 ripe avocado, peeled and cut into 12 thin slices
1 medium tomato, thinly sliced
1/2 small English cucumber, thinly sliced (about 1/2 cup)
How to Make It
To prepare fish, brush fish with oil; sprinkle with 1/2 teaspoon pepper and 1/4 teaspoon salt. Place fish on a broiler pan coated with cooking spray. Broil 6 minutes or until fish flakes easily when tested with a fork or desired degree of doneness.
To prepare tzatziki, combine yogurt and next 5 ingredients (through garlic) in a food processor or blender; pulse until smooth.
Spread 2 tablespoons tzatziki in the center of each flatbread. Divide fish evenly among flatbreads. Top each serving with 2 tablespoons onion, 3 avocado slices, 2 tomato slices, and about 6 cucumber slices; fold in half.
