Salisbury steak. It's really just a fancy name for hamburgers smothered in delicious gravy. As you'll see in the recipe below, it's as easy to make as it sounds. Shape hamburger patties, create a delicious (and super easy) gravy and let it cook for just a few minutes so it all comes together in one delicious entree.
If you don't want to make everything from scratch, use frozen hamburger patties and packaged gravy. It will definitely shave some time off how long it needs to cook. No one is going to judge you. Plus, gravy packets are so good these days that if you want to, you can still tell people it's homemade and no one will be the wiser.
