Six Layer Dinner : Grease a 2 qt. casserole . ( 8 " ) ... place 2 cups sliced raw potatoes , 2 cups chopped celery , 2 cups raw ground beef , 1 cup sliced raw onion , 1 cup of minced green onion , 2 cups of canned tomatoes . Top with green pepper slices ( I season each layer with salt and pepper . Bake at 350 for 2 hrs . ( I cover , but check after 1 1/2 hrs and if looking too " wet " will uncover . Serves six . It really is a nice blend of flavors . Back when , I only had whole toms and would cut them ... today I'd use wedges or cubes . Let me know what you think ! With hard rolls my 5 never complained ! .... this is a 1950s Betty Crocker recipe !
