Preheat the air fryer to 375°F for 2-3 minutes. A hot basket helps the bologna brown quickly.
02 -
Make 3 or 4 short slits around the edge of each bologna slice, or cut a small X in the center. Do not cut all the way through the slice.
03 -
Place the bologna in a single layer. Air fry for 4-6 minutes, flipping halfway through, until hot with browned, crisp edges.
04 -
Place cheese on two of the hot bologna slices and air fry for 30-45 seconds more, just until melted.
05 -
Lightly butter or spray the bread. Air fry for 1-2 minutes until warm and lightly toasted.
06 -
Spread mustard and mayonnaise on the bread. Add the cheesy bologna, extra bologna slices, pickles, lettuce, and tomato if using. Serve right away.
