@thor this is the reason why world vegetarian classics is my favourite cook book (i should just put that in my profile already xD). just "no bullshit"-recipes from everywhere.
it has nothing from norway though, but three christmas casseroles from finland of which one is pretty nice (fermented potato mash which is sweet then).
tl;dr: local classic recipes are great, so are potatoes!
