A quesadilla is made by folding a tortilla around a filling and grilling it until the cheese melts.
The name comes from queso, the Spanish word for cheese. A basic quesadilla uses a corn or flour tortilla and cheese, although regional recipes may include mushrooms, meats, beans, vegetables, or squash blossoms.
In much of Mexico, a quesadilla is cooked on a griddle, commonly called a comal. Some Mexican regions traditionally serve quesadillas without cheese unless the customer specifically requests it, a detail that differs from the widespread international understanding of the dish.
Quesadillas are different from burritos because a burrito is usually a fully rolled tortilla containing a filling. They also differ from enchiladas, which are typically covered in sauce after being filled and rolled. Quesadillas are often eaten as a snack, appetizer, or quick meal.
