Creamed Ground Beef Sos

I loved it when Mom used to make this for us! I have no idea if she originally made it for Dad, who had been in the army, or if she just liked it because it tasted good and was a budget stretcher. A traditional favorite, good ol' SOS. Note: the title of this recipe specifies that it is made ground beef, rather than chipped beef; "authentic" SOS is generally made with chipped beef, however many folks also refer to the ground beef version by the same name.
