Spread the mayonnaise thinly on one side of the four slices of bread.
Place two slices mayonnaise side down in the bin of the air fryer.
Top with two slices of cheese each and then place the top on (mayonnaise side up!) just like you were going to fry it in a pan.
Close the air fryer and select 375 degrees for 3 minutes if using white bread or 375 degrees for 4 minutes if using rye or a similar heavy bread.
When it finishes, flip the sandwiches and repeat for the same amount of time. Serve with a pickle and slice diagonally or in half.
6 minutes for white bread, flipping at 3
7-8 minute for rye and dark breads, flipping at 4 minutes
