Never had a "fried" bologna sandwich. When you all say fried do you mean deep fried or pan fried in a skillet? I’d like to try it.
As for the "curl" We did used to make "boloney bowls" when I was a kid. We’d put a piece of kraft cheese on a slice of OM bologna and put it in the microwave for about 45 seconds. It was a simple and tasty treat for us kids in our early teens.
