Mexico

Walking Taco

A single-serve corn-chip bag, slit open down its long side, packed with taco-seasoned beef, shredded cheese, lettuce, tomato, and sour cream, eaten with a plastic fork from the bag at a fair.

Veggie Burrito

The Mission-lineage vegetarian burrito: a large wheat tortilla rolled around grilled vegetables, rice, beans, cheese, and guacamole, each component covering a different gap left by the absent meat.

Torta

Most of Mexico's filled breads are arguments with one sandwich. The torta's single structural decision is a bean-and-avocado bind that grips the bread and holds everything else in place.
