Sánguche de potito

Sánguche de potito is a traditional sandwich originating from Chile, and it's especially popular in Santiago. The sandwich usually consists of a marraqueta bun that's filled with fried onions, beef or pork intestines, or meat from cow's rectum. The meat is cooked until tender and juicy, and it's then mixed with fried onions and stuffed into the bun. Chorizo sausage is often added to the sandwich, while common condiments include mayonnaise, ketchup, or salsa pebre. The sandwich dates back to the mid-19th century, following the development of the first railroad from Santiago to Valparaiso, when street vendors needed to make fast and hearty food that was easy to eat and prepare.
