A cheese quesadilla is a delicious and simple Mexican dish made by grilling a flour or corn tortilla filled with melted cheese until golden brown and crispy. The cheese, typically a blend of cheddar, Monterey Jack, or Oaxaca cheese, becomes gooey and flavorful when heated. Often served with toppings or dips like sour cream, guacamole, or salsa, a cheese quesadilla can be enjoyed as a quick snack, appetizer, or main dish. Some variations include adding ingredients like jalapeƱos, onions, or beans for extra flavor.
