On medium-high heat in a 2 quart pan, brown ground beef, do not drain any liquid after ground beef has browned. Add 1-1/2 cups of the onions; set aside the remaining onions for later. Add the remaining ingredients and stir everything together. Add enough water to cover the ground beef to the top and allow to boil. Once mixture comes to a boil, lower heat to low and allow to simmer until liquid has boiled down (this may take an hour or more). Stir constantly. When liquid is almost completely gone, mash cooked ground beef with a masher - meat mixture should be finely coarse. Grill the hot dogs (do not boil or steam), place in buns and spoon meat sauce over hot dogs. Add mustard and onions and sprinkle celery salt on top of everything!
