Tacos al Pastor is a classic Mexican dish that originated in Central Mexico. It is made with marinated pork that is cooked on a vertical spit, similar to the way shawarma is prepared. The pork is thinly sliced and served on a corn tortilla, topped with pineapple, onion, and cilantro. The marinade for the pork typically includes a combination of dried chilies, spices, and vinegar, which gives it a tangy and slightly spicy flavor. Tacos al Pastor are often served with a side of salsa and lime wedges for added freshness and acidity.
