Typical lunch/snack foods to pack?

I am planning a hiking trip in July 2018 from Napp to A and plan to buy my supplies in Bodo when I arrive. I am planning on buying oatmeal for breakfast and Real Turmat freeze dried meals for dinner but I'm not sure what type foods are available in Norway for lunch and snacks during the day? I need ideas on lightweight non-perishable foods that can be purchased at Rema 1000, or any other suggested grocery stores in Bodo, that would be good for lunch / snacks while backpacking.

Thank you, Matt.
