Great looking SOS. Any Marines around to argue that it is supposed to be ground meat?
I was thinking the same thing. I've always heard SOS referring to gravy made with hamburger.
Regardless this looks delicious. My Dad only had a few things that he cooked, and chipped beef gravy was one of them. I always enjoyed when Dad made Sunday supper.
I think I'll whip up some gourmet SOS in his honor this week.
