Instructions
Combine the tuna with the mayo. The amount of mayo depends on how thick or creamy you want your tuna. Optional, add pickle relish or diced pickles to tuna mixture.
Butter each slice of bread. Place two to four slices of bread, butter side down, in the air fryer basket.
Layer each slice of bread with tuna, tomato slices, cheese slices, and then top with another slice of bread with the butter side on the outside.
Air fry at 350 °F for 5-6 minutes, or until bread is browned and cheese is melted to your liking. Be sure to flip at the halfway point to make each side evenly cooked.
Carefully remove from the air fryer basket and enjoy!
