"Pastor" in food refers to a type of meat preparation that is commonly used in Mexican cuisine. Specifically, "al pastor" is a dish made with seasoned and marinated pork that is slow-cooked on a vertical rotisserie called a "trompo". The dish is believed to have originated in the Central Mexican region of Puebla and Mexico City, and it is based on the lamb shawarma brought by Lebanese immigrants to the region. The marinade for al pastor typically includes ingredients such as dried chilies, spices, and pineapple. Once fully cooked, the meat is sliced thinly and served on tortillas with simple toppings such as cilantro, onions, lime juice, salsa, and occasionally pineapple. Al pastor is a popular street food in Mexico and has spread to the United States.
