Step 1

Mash the avocado and mix in the chopped roasted red peppers.

Step 2

Butter one side of each slice of bread. Place 4 slices buttered side down in the air fryer basket. (Don't overcrowd the basket - if yours is small you many need to cook these in 2 batches.)

Step 3

Place a slice of cheese on the bread (optional step if you are using 8 slices of cheese).

Step 4

Distribute the avocado mixture on each piece of bread then place a slice of cheese on top.

Step 5

Top the cheese with the remaining pieces of bread, buttered side up.

Step 6

Preheat the air fryer to 400 F. Air fry for 6 minutes, then flip the sandwiches and air fry for another 3 minutes. (Time may vary due to differences in air fryers.)
