Preheat cooking oil in a medium-sized frying pan over medium heat.

Lay out one chicken breast.

Place one slice of ham on top of the chicken breast.

Place a half slice of Swiss cheese on top of the ham.

Roll the chicken breast around the ham and cheese.

Secure the roll with toothpicks.

Repeat the layering and rolling process for the remaining chicken breasts, ham, and cheese.

In a shallow dish, beat the eggs.

In another shallow dish, place the bread crumbs.

Dip each chicken roll into the beaten eggs, ensuring it is fully coated.

Roll the egg-coated chicken roll in the bread crumbs, ensuring it is fully covered.

Carefully place the breaded chicken roll into the preheated cooking oil.

Fry the chicken roll until it is browned and cooked through, about 15 minutes.

Remove the cooked chicken roll from the frying pan and drain on paper towels.

Remove the toothpicks.

Serve hot with your favorite wine sauce poured over the top.
