Any suggestions for cheap meals made from ingredients that keep well without fridge or freezer?

I live in a forest camp which is a long way from the nearest supermarket. I have to do my shopping in bulk every few weeks. I am getting pretty bored of just eating the same old things. If anyone has any ideas for cheap, healthy meals made from long life foodstuffs I am all ears. I do have a small amount of fridge freezer space but really most of my food has to be packets and tins :/.
