Taco
A taco is a mexican-style entree that consists of either a tortilla (soft) or a nacho (normal) style shell stuffed with beef, steak, chicken, or other meat; cheese; beans (frijoles); lettuce; tomato and may have sour cream, guacamole, salsa, corn or other peppers and spices added. It is similar to a burrito but the primary difference is that the burrito is wrapped and may be covered with salsa, cheese, or other topping and tacos are usually "open" (not wrapped). Burritos are also often larger than tacos and may contain rice as well.
The taco has been adapted in many forms in the United States as well as in other parts of the world. Many fast food chains have developed or adapted the taco to a unique style: Taco Bell and Chipotle are two of the major chains in the US that provide their own unique spin on the taco and burrito.
