Cube steak with mushroom gravy is a classic comfort food dish. To make it, season the steak with salt, pepper, and garlic powder. Dredge the steak in flour and fry it in a skillet with oil until it is golden brown and crispy. Remove the steak from the skillet and sauté sliced mushrooms in the same pan. Add beef broth and flour to make a gravy and serve it over the steak.
