My Dad was a 20 year Navy veteran, worked his way up through the ranks to CWO2. We often had SOS, the chipped dried beef type , also the creamed tuna on toast or noodles;whatever Mom had on hand. I'm one of 5 kids, so meals that fed lots of kids and was cheap was important.
I've not had either of these dishes in years, I might just have to make some, but with the hamburger rather than the dried beef in the jars.
