Step 1

In a small bowl, mix the mayonnaise and pesto until well combined.

Step 2

Spread 1/2 tablespoon of the pesto mayo on each slice of Texas toast. To the bottom slice of each sandwich, layer on a slice of Cheddar, then a slice of mozzarella, followed by a second slice of Cheddar. Top each with the second slice of bread, spread-side down. Spread the remaining mayo mix on the outside of both sandwiches, top and bottom.

Step 3

Air-fry both, flipping halfway through, until golden and crisp, about 6 minutes.

Step 4

Slice in half and serve.
