For the steak: Trim any remaining fat off the steaks and, using a mallet or rolling pin, pound out the steaks to 1/4-inch thick.
Beat together the milk and egg in a shallow dish and set aside. Place the flour in a shallow dish, season well with the seasoning salt and pepper and set aside.
Cover the bottom of a large skillet, preferably cast iron, with enough oil to reach about 1/2-inch up the pan. Heat over medium-high heat.
Coat the steaks in the egg mixture, then the flour and then add to the pan. Cook until the juices begin to surface and the bottom is nice and brown, 2 to 3 minutes. Flip the steaks and cook another 2 to 3 minutes more. Be careful to not overcook. Continue this process until all the steaks are cooked, placing the finished steaks on a paper towel-lined baking sheet.
After frying the steaks, prepare to make the gravy: Let the drippings in the pan sit until the excess browned bits of seasoning settle to the bottom of the skillet. Pour off most of the oil, leaving about 4 tablespoons behind with the brown bits. Add the flour, stirring until well mixed. Place the skillet back over medium-high heat and slowly add the milk while stirring constantly. Cook until the gravy comes to a boil. Season with salt and pepper. Serve with chicken fried steak.
