What is "pambazo"?

Pambazo is a type of Mexican sandwich that is made using a soft white bread roll that is dipped in a red guajillo pepper sauce and then filled with a variety of ingredients such as potatoes, chorizo, refried beans, lettuce, and cheese. The sandwich is then toasted on a griddle until crispy and golden brown on the outside and hot and flavorful on the inside. Pambazo sandwiches are often sold by street vendors in Mexico and are a popular snack or lunch item. They are known for their spicy and savory flavors and are often served with a variety of toppings such as sour cream, fresh salsa, or pickled jalapenos.
