Burritos, originating in Mexico, are flour tortillas filled and folded into rectangular-shaped packages. Fillings vary and may include combinations of refried beans, shredded meat, poultry, chorizo, cheese, lettuce, tomatoes and sour cream. Breakfast burritos may be filled with seasoned scrambled eggs or a fruit mixture. Burritos are served without a sauce but may be garnished with sour cream or salsa.
