How to Make It
Lightly coat a grill pan with oil; heat over medium-high. Place pita rounds, 2 at a time, on grill pan; cook, turning once, until warm, about 3 minutes.
Toss together cucumber, tomatoes, olives, feta, onion, and salt in a medium bowl.
Spread 2 tablespoons hummus on each pita round; top each with ¾ cup cucumber salad.
