01 - Split four bagels and lightly oil the cut surfaces. Divide the cup of sauce among eight halves, about two tablespoons each.
02 - Add one-quarter cup mozzarella to each half, then divide pepperoni and seasonings over them.
03 - Air-fry in uncrowded batches at 375°F for roughly five to six minutes, until cheese melts and the centers are hot. Check early in small appliances.
04 - Let stand briefly before serving; sauce beneath the cheese stays hot.
