Leftovers don't have to be drab. Use lamb in a Mediterranean-style wrap.
In a small bowl, combine yogurt, olives, garlic, oregano, salt, and pepper.
Thinly spread some of the yogurt mixture over the lavash; then layer half of each lavash with lamb, cucumber, and red onion slices. Spoon remaining yogurt sauce over filling; fold each lavash to enclose.
