Pambazo is both the name of a Mexican bread and the name of the sandwich made using that same bread. Its name stems from pan basso, a type of peasant bread reserved for the lower classes through history. The bread is commonly dipped in a spicy, pepper-onion-garlic sauce called guajillo, giving the sandwich a unique, bright orange color.
Typically, the sandwich is filled with ingredients such as potatoes, refried beans, avocado slices, chicken, and chorizo sausage, but during Lent, street vendors often substitute the meat with cheese. Pambazos are especially popular in the area of Puebla and Veracruz, and it is said that they make a great light supper, especially when paired with a freshly prepared salad on the side.
