Now lay down a cheese slice.
Add a quarter of the tuna salad and spread it over the bread and cheese evenly.
Add a second slice of cheese over the tuna.
Finally, put down the top bread slice, butter side up.
Air fry the tuna melt in the air fryer for 6 minutes total, flipping the sandwich every 2 minutes, or until the cheese is melted, bubbly, and golden brown.
