I've got a couple of favorites.
Salisbury Steak w/ Mushroom Sauce:
Ground Beef
Chopped Green/Red Peppers
Chopped Onion
Garlic
Fresh Bread Crumbs (1 to 1 1/2 cups)
Egg White
Steak Sauce
Combine and shape into patties (I use my tupperware patty shaper). Broil in oven, until cooked to your liking.
Create a mushroom sauce with mushrooms, butter, shallots, dry white wine, flour and beef broth. We serve this with egg noodles.
The item below doesn't really have a name, it is a dish my dad ate alot during the Depression.
Ground Beef sauteed with onions and garlic. Add one can each of drained corn, green beans, wax beans. Add between one and two cans of tomato sauce and let simmer. Should be about same consistency of sloppy joes.
We serve this over mashed potatoes.
