This is a flavorful chicken dish, which I first tasted at a little Lebanese restaurant. While normally shawarma is sliced off a rotisserie, it can be made at home with just a few changes. Be warned, it takes a day of prep time. For lunch, serve as a sandwich in warmed flatbread with cucumber sauce, sliced onion, and seeded tomato. For dinner, serve with rice and lentils (for a treat, look up mujadarrah on this site).
