This is a great experiment in eating a months worth of dehydrated and freeze dried meals.

Ive gone with 20 kilo buckets of the following sealed in mylar bags.

oats

honey

yellow split peas

red lentils

haricot navy beans

chick peas

basmati rice

polenta

potato flakes

salt

pinto beans

borlotti beans

cannalini beans

flour

sugar brown

powdered milk

Id supplement the above list with ready wise dried vegetables and fruit and a tub of mains and breakfasts. which are mainly pasta dishes and granola. I like the on track meals along with the outdoor gourmet meals. One day Id cook rice and beans and mix vegetables in with it for example, then next have a pasta meal. Mix it up as much as possible.I like the ready wise grab bags for in vehicles.
