take however much hamburger (i usually use either a pound or 2 and divide for the freezer) and put it in a big bowl. add 1 egg per 1/2 pound of meat (this binds it all together) and add as much onion/garlic/pepper/parsley as you would for spaghetti sauce. if you use onion/garlic powder, mix it up some now. if you use "the real thing" you can wait to do the mixing. then add either dale's steak seasoning or Worcestershire sauce (i use a couple of tablespoons, i think, i don't measure, i "splash"). mix it a bit. then add about a 1/2 cup of bread crumbs (or do what i do, and add stale bread/rolls that are pulled into small bits). mix well and mold to whatever pan you are baking it in. if you are making some for the freezer, like the pan with wax paper and mold the first one, take it out and wrap in the wax paper to freeze, then put what you are baking in the pan. less mess and the frozen one will fit right in the pan! bake at 350 about an hour, until done.
some people add either ketchup, tomato sauce, or bbq sauce on top when baking, either the whole time or the last half. i don't.
i bake mine in the toaster oven all the time, comes out fine and saves me electricity. i have a corning ware pan that fits perfectly. hope this works for you!
