IIRC, clif makes a new sort of savory bar, so you could take some of those sweet bars and mix them with the savory ones for a change.
Everyone has made great suggestions.
I would go with turkey jerky, tuna, clif bars, some sort of fruit roll up, granola/gorp,tortillas (they have an amazing shelf life), peanut butter and raisins.
I would also make sure that I had access to sterlized water.
Having just spent 5 days on an island with UHT milk, I realized how bad it tastes, but how nice it is to have it with my coffee. I know you can get it in little cup sized tetra packs.
