I make the dehydrated hamburger as discribes. Buy as lean as possible, brown and run hot or boiling water over it and dehydtrate. I canoe camp alot, but I take this as it will last a long time. It does take 15 mins. to rehydtrate and works well with hanburger helper or spagetti if simmered for a while.
Another good idea is the tuna and chicken in foil pouches.
