Australian here: Cheese and Vegemite (yeast extract) sandwiches are what a lot of people grew up having for their school lunches. My kids like it because it's quick to eat. For the Norwegians, is Jarlsberg your typical cheese in a matpakke? Probably my favourite sandwich cheese!
I still generally eat a vegemite sandwich for lunch every day, but these days it's nicer bread with vegemite, cheese, avocado, and tomato.

My kids love their avo and will often make their own eggs and avocado on toast for breakfast.
