If you're looking for a more substantial grilled cheese sandwich, try this pesto chicken air fryer recipe. Start by cooking chicken breast in the air fryer until cooked through. Remove the chicken and shred it. Butter two slices of bread and spread pesto sauce on one side of each slice. Layer the shredded chicken and your favorite cheese on one slice of bread. Place the sandwich in the air fryer and cook at 375°F for about 5 minutes, or until the bread is toasted and the cheese is melted. The combination of savory chicken, flavorful pesto, and melted cheese is simply irresistible.
