I heard about ‘shit on a shingle’ from mother, an army wife in the fifties. Unimpressed, she was, but she was a farm girl during the depression. She and Grammaw both turned out fine chow for this growing boy...
I’ve heard that the polite term is ‘Same Old Stuff’.
This was a family favorite growing up. My dad (Army Air Corps) called it S-O-S a few times but out of respect for my mom politely called it “dried beef gravy.”
I can’t have it very often now because of the salt.
