Al pastor (from Spanish, “herdsman style”), tacos al pastor, or tacos de trompo is a preparation of spit-grilled slices, usually pork originating in the Central Mexican region of Puebla and Mexico City, where they remain most prominent; today, though, it is a common menu item found in taquerías throughout Mexico. The method of preparing and cooking al pastor is based on the lamb shawarma brought by Lebanese immigrants to the region.
