How to Make It
Form the beef into 16 ½-inch-thick patties and season with the oregano, ½ teaspoon salt, and ¼ teaspoon pepper.
Heat 1 tablespoon of the oil in a large skillet over medium heat and cook the patties, 2 minutes per side for medium.
Top the pitas with the hummus, patties, onion, and parsley. Drizzle with the remaining tablespoon of oil and serve with the lemon wedges.
