I first heard of bologna when I was reading the book The Shipping News (you might have seen the movie) where Quoyle, the main character, moves to Newfoundland to reconnect with his roots. Most food the local diner offers comes from a can.
"Quoyle ordered the fried bologna dinner. It was the only thing on the menu he hadn't tried, but night after night he'd watched diners at neighboring tables wolfing and gnashing, guessed it was a house specialty. The plate came heaped with thick bologna circles, fried potatoes and gravy, canned turnip, and a wad of canned string beans, all heated in a microwave. The overwhelming sensations were of sizzling heat and salt content off the scale."
I googled it and thought "what a treat".
