Burrito is a dish consisting of a wheat flour tortilla that is wrapped in such a way that it is possible to fully enclose the flavorful filling on the interior. The filling consists of a combination of various ingredients such as meat, beans, rice, lettuce, guacamole, and cheese, among others.
Its name means little donkey in Spanish, and a popular theory suggests that it stems from the way the bedrolls and packs appeared on the donkeys that carried them. Some claim that the dish originated in the 19th century by either the vaqueros in Northern Mexico, farmers in California, or the miners from Sonora.
The first appearance of burrito in American restaurants was recorded in the early 1920s in Los Angeles, when the owner Alejandro Borquez opened the Sonora Café and started serving the dish. He changed the name of the restaurant to El Cholo Spanish Café, and it's still in business.
