Back when we did a lot of backpacking, our favorite first night meal was, um, it never got a name. Anyway, we'd take a pound of frozen hamburger, brown it, add a bunch of Minute Rice, water, and a packet of dried vegetable soup. One pot, and all the nutrition we felt we needed. It's a very flexible recipe. The meat can be anything you want, a can or foil packet of tuna, pre-cooked chicken, whatever. I like the starch to be quick cooking, hence the Minute Rice. Cous cous would work well, as would noodles, if you want to take the time. I got the vegie soup mix from out local health food store, but wasn't too worried about sodium. After all, we were working pretty hard and sweating.

Those small packets of muffin mix make good pancake-like things in the morning. There is just the right amount of mix for a two-person meal there.

Eggs, both raw and hard-boiled travel better than you think, and last for days if kept reasonably cool.
