Remove the soft brown bread crust from the soft white bread.

Flatten the bread with a rolling pin and place the plastic sheet under it.

Put the prosciutto, mozzarella, and grated Parmigiano cheese on the bread.

Immediately roll up the white bread and the plastic food wrap from the narrow end.

Close the ends of the plastic food wrap as in the picture below.

Place the rolls in the refrigerator for 1 hr to let them take shape.

Prepare two plates, in one put beaten eggs with a pinch of salt, in the other put breadcrumbs, pass the rolls first in the egg then in the breadcrumbs, letting the breading adhere well all around.

Fry the rolls in a pan in plenty of hot oil, the oil must cover the entire roll so that the browning is homogeneous.
