Preheat oven to 350°F (175°C).

Pound veal or pork cutlets to 1/4-inch thickness.

Place one slice of ham and one slice of mozzarella cheese in the center of each cutlet.

Roll up each cutlet tightly, starting from the narrow end.

Secure the rolls with wooden picks to prevent unraveling.

In a shallow dish, combine flour, salt, and pepper.

Coat each roll thoroughly in the flour mixture.

Dip each floured roll into the beaten egg, ensuring it's fully coated.

Roll the egg-coated rolls in dry bread crumbs, pressing gently to adhere.

Heat oil in a skillet over medium heat.

Fry the breaded rolls in the hot oil until golden brown on all sides.

Transfer the fried rolls to a baking sheet.

Bake in the preheated oven for 15 to 20 minutes, or until cooked through and cheese is melted.
