Somehow, chipped beef gravy got to be known as S.O.S. in the Navy and to all but us old timers. Well it ain't !! The real thing is made with a base of ground beef and a few other things. After messing up 5,000 lbs of burger and 30 years of searching I found this basic recipe in the May 2005 issue of The American Legion magazine letters section. It's for 15+ people but it freezes quite well for later use. In the Navy, this was a breakfast dish, but I've used it for every meal. Measurements are close enough to be good.
