Mix the ground meat with 1 egg, the day-old bread soaked in water and squeezed dry (preferably without the crust), salt, pepper, chopped parsley, and the cheeses.

Take portions of the mixture and shape them into supplì, leaving a hollow in the center for the filling.

Place a piece of smoked scamorza cheese and a piece of spicy mortadella inside each.

Seal the supplì. Once all are formed, beat the remaining egg in a plate, roll each supplì in the egg, then coat with breadcrumbs.

When ready, heat the oil. Once it reaches temperature, fry the supplì until golden brown.
