A quesilla (not to be confused with a quesadilla) is a hot toasted sandwich of melted Mexican string cheese, ham, avocado, onion, tomato, and jalapeño peppers. Mexican string cheese, also known as Oaxacan cheese, is similar to mozzarella cheese in color and texture but has a saltier flavor. You can substitute mozzarella or other string cheese if you wish.
