Pre-heat oven to 350℉.
Season chicken with salt, pepper and garlic powder.
Lay a strip of cheese in the center of each piece of chicken. Tuck the sides of the chicken in and roll up the lengthwise, jellyroll style. You may want to secure with a wooden toothpick.
Combine the flour with 1 teaspoon paprika, ½ teaspoon of salt, ½ tsp. garlic powder and ¼ teaspoon pepper in a shallow bowl. Next combine breadcrumbs with ½ teaspoon of salt, ½ teaspoon garlic powder and ¼ teaspoon pepper in another shallow bowl. Finally, beat the egg with milk in a third bowl.
Dredge each chicken roll in the flour, then in the egg mixture and finally in the breadcrumbs.
Heat the oil and butter in a large ovenproof skillet over a medium-high heat. Cook the chicken rolls about 3 minutes on each side until golden.
Then place in the oven and bake for 10 minutes.
Top with marinara sauce. Sprinkle with parmesan cheese and parsley.
