homemade Southbury steak. You're going to ground beef, mushrooms, onion, mushroom gravy, brown gravy, and some bread crumbs. Now take your onion and finally mince it up. Take your ground beef, onions, and bread crumbs, and some salt and pepper. Get it all mixed up. Paddy it out. Then you want to serve your patties. Oh look at that. Now make your gravy. I use a little bit of milk. Add your mushrooms. Now take your served patties, add to your gravy and allow to finish cooking for about 45 minutes. Mmm. And there you have it.
