The timeline of the burrito documents the use of the burrito, a food made with tortillas and filling found in Mexico and the United States. Hand-held take-out foods like the burrito have a long history. Before the Spanish colonization of the Americas, indigenous peoples were eating hand-held snack foods like corn on the cob, popcorn and pemmican. In Mexico, the Spanish observed Aztecs selling take-out foods like tamales, tortillas, and sauces in open marketplaces. The Pueblo people of the desert Southwest also made tortillas with beans and meat sauce fillings prepared much like the modern burrito we know today.
