Tostada is a Mexican dish consisting of toasted tortillas (hence the name) filled with various meats and vegetables. The dish is often topped with melted cheese, although there are numerous variations of tostada recipes throughout Latin America.
In Mexico, tostadas are usually filled with shredded chicken, beans, chilis, lettuce, and avocado slices. Traditionally, the tortilla is slightly creased, a practice that originated from the need to use up tortillas that were not so fresh.
