Banh mi heo quay is a traditional banh mi sandwich variation made with roasted pork belly as the main ingredient. The pork is roasted with a thick layer of salt and spices, then sliced and served on a freshly baked banh mi roll.

The sandwich is then dressed with a combination of mayonnaise, pickled carrots and daikon, cucumbers, cilantro, and chives. If desired, sliced chili peppers can be added to the sandwich as a topping, making it very spicy. One side of banh mi heo quay can also be spread with chicken liver pate before the sliced pork belly is added to the sandwich.

This type of banh mi can be bought at street food stalls and its one of the most popular types of banh mi in Vietnam, according to TasteAtlas.
