Back in the 1980s one of the meals in the then MRE was a pork patty.
Sweet Jesus that think was absolutely foul....
My roommate was ROTC and he would bring back MREs.
The meatballs in BBQ sauce weren't bad, nor was the beef stew. The chicken a la king was... meh.
The other one that was pretty bad was some sort of ham loaf.
But the pork patty? Satan's hockey puck, or simply Satan's ass.
