A quesadilla is a popular Mexican dish made primarily of a tortilla filled with cheese and other ingredients. The tortilla is usually made from corn or flour and is folded in half to enclose the filling. Common additions include meats, beans, vegetables, and spices, which enhance the flavor and texture. Quesadillas are often cooked on a griddle or skillet until the cheese melts and the tortilla becomes crispy. This dish is versatile and can be served as a snack, appetizer, or main course. It is often accompanied by sides such as salsa, guacamole, or sour cream for added taste. Quesadillas are enjoyed in various regions, with each area having its own unique variations and ingredients.
