Preheat the oven to 350°F (175°C).

Remove the skin from the chicken breasts and discard.

Place each breast between two pieces of wax paper and flatten them with a wooden mallet until quite thin.

Cut each flattened breast into 2 pieces crosswise.

Season each piece with salt and pepper to taste.

Place a slice of Swiss cheese and a slice of ham on each piece of breast, then roll them up.

In a shallow dish, mix the beaten eggs with water.

Dip each rolled chicken piece in the egg mixture, then in flour, then in egg again, and finally in bread crumbs, ensuring they are well coated.

Melt the butter in a flat baking dish, then place the coated chicken rolls in the dish.

Bake the chicken in the preheated oven for 20 minutes or until lightly browned.

Serve hot.
