RE: Ground Steak Sandwiches
This sounds revoltingly like what was often served to me in the Navy and called, even officially I think, "sh_t on a shingle". That was a variation on creamed chip beef but used ground beef rather than chipped beef. The real old salts just dumped a lot of Tabasco on it and downed it.
Although I always assumed military cooks invented this, a lot of military food is based on Southern cooking since such a high proportion of the military is of Southern origin and so it could have come from NC (and if you're from NC, don't get mad at me for saying so--you live in one of my favorite states and one I called home for 4 years myself).
