Split your hoagie rolls open. Place them in your air fryer basket. You might need to do this in two batches if your air fryer is small like mine.
Put 4 meatballs into each roll.
Pour the marinara sauce over the meatballs. Don't be shy with it.
Add a big pile of mozzarella cheese on top of the sauce.
Lay your pepperoni slices over the cheese. A little extra pepperoni never hurts anyone, right?
Sprinkle a little dried oregano over the top for that classic pizza smell.

Pull them out carefully and serve while they are hot.
