When I was a kid, we didn’t have smartphones or the internet — all we had was a TV. But we didn’t care because as we watched, we got to enjoy a little something called a “TV dinner.” The king of those dinners, in my opinion, was the Salisbury steak, which is what I’ll show you how to make here, along with one of the greatest gravies ever invented. Serve with buttered mashed potatoes and a vegetable side of your choice.
