Peanuts aren't nuts...
I carry several of the foil packages of tuna, a coupule of chicken, some rice (instant and regular) dried apricots, lipton oinion soup mix (makes anyhing taste good,) salt sugar and spices. Small noodles (must be small and hard) also work well. Grits (instant) and instant oatmeal. Several pkgs of hot choc mix - can use either hot or cold. A jar pf peanut butter and a tube of honey.
THis is the "meal" stuff. I also carry a supply of gorp (my mix) and jerky (beef, venison, whatever's on hand.)
This is not as heavy as you might think, since the meat is the heaviest part and there is little spare moisture in it.
