So easy to make and no mess! My favorite Italian deli made a similar sandwich but unfortunately they closed down, so I decided to make a dupe in my air fryer. This makes a very filling lunch, or you can cut it in half and share if pairing with a bowl of soup.
Preheat the oven to 360 degrees F (180 degrees C).
Butter one side of a slice of bread and place it on a plate, buttered side down. Evenly top with prosciutto and mozzarella slices. Butter the second slice of bread and place on top, keeping the buttered side facing out.
Place in the air fryer and cook until lightly browned and toasted, about 8 minutes.
