Al pastor is a traditional Mexican dish made with seasoned and marinated pork. The name "al pastor" translates to "shepherd style" in Spanish, and it is believed to have originated from the lamb shawarma brought by Lebanese immigrants to Mexico in the early 1900s. The method of preparing and cooking al pastor is based on the Lebanese shawarma, but it features a flavor palate that uses traditional Mexican adobada (marinade) .

Al pastor meat is taken from boneless pork shoulder. It is slow-cooked on a vertical rotisserie called a trompo, which is similar to the Lebanese shawarma spit-roasting method. The meat is marinated in a combination of dried chilies, spices, and pineapple, which gives it a unique flavor. Once fully cooked, the meat is removed from the spit in very thin slices and served on tortillas with simple toppings such as cilantro, onions, lime juice, salsa, and occasionally pineapple.

In summary, al pastor is a type of Mexican meat made with seasoned and marinated pork that is slow-cooked on a vertical rotisserie and served on tortillas with simple toppings.
