FREEZER BAG COOKING
As a staple that I relied on while hiking the AT was a carb rich meal like this... Start with a bag of Knorrs rice or noodles side dish, they cost about $1.00 each, rip it open dump it in a zip lock FREEZER bag (add freeze dried bulk meats if wanted) squish out air, zip it up and pack them away. When ready add 10-12 oz boiling water, stir it up, let sit in a cozy which is basically a tin foil and bubble wrap and duck tape pouch that will work just fine, there are commercially made pouches available, supplement with pouch meat if wanted. Best part comes now, just EAT and clean spoon then properly dispose of just a bag. Later on eat a Snickers before bed and move on in the AM.
