Potted Meat? Seriously, it is the single most disgusting thing they sell in the grocery store- pickled pigs feet included. My MIL makes potted meat sandwiches and my husband loves them. I make it for him every now & then but gag the entire time. I can't believe enough people eat it to keep the companies making it.
ETA: MIL taught me to make potted meat sandwiches for DH. You take 2 or 3 hard boiled eggs, 2 cans of potted meat, a scoop of pickle relish, and about 1/4 cups of Miracle Whip- mix them together and chill. Then you spread it on bread.
My kids hate it. He keeps trying to convince them it's good. I tell him it's a losing battle.
No one I talk to ever has any idea what it is. It's not SPAM but is sold next to it. But I am genuinely shocked to find other people who know what it is.
