A flour tortilla filled with a savory mixture, then folded in half to form a half-moon shape. The filling can include shredded cheese, cooked meat, refried beans or a combination of items. After the tortilla is filled and folded, it's toasted under a broiler or fried. Quesadillas are usually cut into strips before being served, often as an appetizer.
