When we backpack we usually do freezer back meals. I will by freeze dried in bulk to assemble meals in quart freezer bags or dehydrate stuff to assemble the meals. I also like to use Lipton noodles or rice and foil pack tuna or chicken. Just add water and tuck the bag in a Reflectix cozy for 15-20 minutes and you're good to go. We are in the process of planning a Boundary Waters trip for late August and I am going to get some heavy vacuum seal zip top bags to try. In theory if I can start assembling meals now and vacuum seal them they will stay fresh a lot longer.
I had to google reflective cozy. Purty kool.
