Salisbury steak is a retro dinner that is making a comeback. The dish was invented by Dr. J.H. Salisbury in the late 1800's as a way to promote eating a low carb diet. Salisbury steak became popular with the introduction of the T.V. dinners. Until now, the dish has all but disappeared except in the frozen food section of the grocery store. Salisbury steak is not steak at all but a burger patty topped with a luscious brown gravy made with mushrooms and onions. It is traditionally served alongside simple buttered egg noodles or mashed potatoes and vegetables. Revive this blast from the past dish and make it for dinner tonight!
