Living near the dutch border, you get "kaassouffle" in a lot of places. Its basically breaded, deep fried gouda cheese. While I love them, I always warn friends tasting them for the first time - they can really ruin your mouth.
Kaassouffle is great and i don't know why it hasn't spread to higher-altitude parts of the world. I found the key to eating it safely was to have a glass of cold beer to hand.
In italy something very similar (sofficini) is quite common, but associated to kids food.
They also sell them with various additional fillings, such as cheese and ham, mushrooms, mozzarella and tomato (becoming something like Pizza rolls, I guess)… i always wondered why there’s really only one type of kaassouffle, really.
