Preheat the oven to 400 degrees F. Lightly grease rimmed baking sheet. Place the round steaks between two sheets of waxed paper and pound to 1/8-inch thick using a meat mallet or rolling pin. Set aside. In a shallow dish, combine the flour, seasoned salt, and bread crumbs. Mix well. In another shallow dish, whisk together the egg whites and milk. Dip each piece of steak in the bread crumbs, coating well and pressing the crumbs on so they adhere. Then dip the meat in the egg mixture, coating completely and letting any excess liquid drip off. Then, again dip the meat into the crumbs and coat well. Place the coated steaks on the baking sheet. Spritz with non-stick cooking spray or olive oil. Place the baking sheet in the oven and bake at 400 degrees F for 10 minutes. Turn the steaks over and spray again with cooking spray. Bake for 10-12 more minutes or until the coating is crisp and lightly browned. While the chicken fried steak is in the oven, place the gravy in a microwave safe dish and microwave for 2 minutes or until heated. To serve, place one steak on each plate and top with about 1/4 cup of gravy. Serve hot.
