The quesadilla has its origins in colonial Mexico. The quesadilla as a food has changed and evolved over many years as people experimented with different variations of it. Quesadillas are frequently sold at Mexican restaurants.
A quesadilla or sometimes specifically a cheese quesadilla, is a Mexican dish, consisting of a tortilla that is filled with cheese and then grilled. Traditionally, a corn tortilla is used, but it can also be made with a flour tortilla, particularly in northern Mexico and the United States. Other ingredients are often added, such as savory mixes of spices or vegetables, before the quesadilla is cooked on a griddle.
A full quesadilla is made with two tortillas that hold a layer of cheese between them. A half is a single tortilla that has been filled with cheese and folded into a half-moon shape.
