Preheat the oven to 375°F (190°C) and grease a baking dish.

Pound each chicken breast between plastic wrap to about half an inch thick.

Layer ham and Swiss cheese on each chicken piece, then roll tightly and secure with toothpicks.

Set up a breading station: one bowl with seasoned flour, one with beaten eggs, and one with panko breadcrumbs.

Dip each rolled chicken piece first in flour, then into the egg, and finally coat with panko.

Arrange the breaded rolls in the greased baking dish, drizzle with olive oil or melted butter, and bake for 25-30 minutes until golden brown.
