Make this a heartier meal by adding a few slices of bacon to the sandwich, avocado slices, or on inside of slices, spread bread with pesto sauce before adding cheese.
Depending on the type of bread you use, you may want to adjust the cook times. For softer bread, or French Bread, air fry until it reaches your desired crispness.
