Cube steak and gravy is a classic comfort food dish that is easy to make. Season the steak with salt, pepper, and garlic powder. Dredge the steak in flour and fry it in a skillet with hot oil until it is golden brown and crispy. Remove the steak from the skillet and make a gravy by whisking together flour, beef broth, and milk. Serve the steak with the gravy and mashed potatoes for a delicious meal.
