How to Make It
Heat broiler. Toss the steak, bell peppers, and onion with the olive oil and ground coriander; season with ¾ teaspoon salt and ¼ teaspoon pepper. Thread onto 8 skewers and broil, turning occasionally, until cooked through, 6 to 8 minutes.
In a small bowl, mix together the yogurt and lemon juice.
Serve the kebabs with the pitas. Top with the yogurt sauce, mint, and hot sauce.
