A Quesadilla (IPA , usually anglicized as ) is a dish in Mexican cuisine or Tex-Mex, which involves cooking ingredients, most importantly cheese, inside a corn or wheat tortilla or a wrapping of masa dough. The word comes from Spanish, and literally means "little cheesy thing" (from queso, or "cheese", + ada, an adjectival suffix, + illa, a diminutive suffix). Exactly what constitutes a quesadilla varies from region to region and between the U.S. and Mexico, and is not universally agreed upon by chefs, but there are certain similarities between the different versions that people generally agree upon, namely that the quesadilla is cooked after being filled or stuffed, while a taco or burrito is filled with pre-cooked ingredients. The purist faction may argue that only the folded-masa, empanada-style Mexican version is a "real" quesadilla, but some well known chefs such as Rick Bayless make more liberal interpretations.

However, variations include the use of wheat flour tortillas, especially in the northeast part of Mexico, which are more like cheese tacos found in the U.S. Wheat dough is used in place of corn masa in pastes, a preparation typical of the Mexican city of Pachuca, Hidalgo.Quesadillas can be stuffed with ingredients other than just cheese. This stuffings may include: pumpkin flower, sausage, chicken, ham, refried beans, potatoes, mushrooms, scrambled eggs, etc. Salsas can also be added to spice up the flavor.The sincronizada (Spanish for "synchronized") is a tortilla dish frequently confused with quesadillas by tourists because it is what is typically called a quesadilla in most Mexican restaurants outside of Mexico. Sincronizadas are made with a flour tortilla covered with cheese and then covered with another flour tortilla. And usually other ingredients like carne asada, ham or chorizo are used, just like in regular quesadillas.
