1. Preheat Oven:

1. Preheat your oven to 375°F (190°C). Lightly grease a baking dish or line it with parchment paper.

2. Prepare the Chicken:

1. Place each chicken breast between two sheets of plastic wrap or parchment paper.
2. Using a meat mallet or rolling pin, pound the chicken to an even thickness (about 1/4 inch thick).

3. Add the Filling:

1. Lay a slice of ham and a slice of cheese on each chicken breast.
2. Roll the chicken tightly around the filling, tucking in the sides as you go. Secure with toothpicks if necessary.

4. Bread the Chicken:

1. In a shallow dish, mix the flour, garlic powder, paprika, salt, and black pepper.
2. In a second dish, place the beaten eggs.
3. In a third dish, combine the breadcrumbs and Parmesan cheese.
4. Dredge each chicken roll in the flour mixture, then dip in the eggs, and coat with the breadcrumb mixture.

5. Bake:

1. Place the breaded chicken rolls seam-side down in the prepared baking dish.
2. Drizzle the melted butter over the top of the chicken.
3. Bake for 25-30 minutes, or until the internal temperature reaches 165°F (74°C) and the breadcrumbs are golden brown.

6. Serve:

1. Remove toothpicks (if used) and serve warm. Pair with a creamy Dijon sauce or your favorite sides.
