Quiche was mentioned earlier. My mom experimented with that once and put too much dried mustard in it. We called it Egg Pie. It was one of the few things that we did not have to eat. And it became one of those long-running family jokes.
Liver was never a favorite. My brother hid the package once under the sink. After a few years went by of liver revolt by the kids, my dad would grill it outside and serve it with bacon. At last it was ok.
Chef Boyardee ravioli was my go to favorite to take on boy scout camping trips and heat up in the little pot that came with the mess kit.
Beef tongue was always a treat - served with tomato sauce.
