Tacos al Pastor is one of the most popular Mexican dishes. It consists of thinly sliced marinated pork that is cooked on a vertical spit, similar to the way shawarma is prepared. The pork is typically marinated in a mixture of spices, including achiote, garlic, and various chili peppers. Once cooked, the meat is sliced and served on small tortillas, topped with pineapple, cilantro, and onions. The combination of the tender, flavorful pork with the sweet and tangy pineapple creates a delicious and satisfying taco.
