What is shawarma and how is it prepared?

Shawarma is a Middle Eastern dish made of thinly sliced meat (usually lamb, chicken, or beef) that is marinated in spices and then stacked on a vertical rotisserie. The meat is slowly cooked as it rotates, allowing the outer layers to become crispy while the inside remains tender. Once cooked, the meat is shaved off the rotisserie and typically served in a pita or wrap with vegetables, tahini sauce, and other toppings.
