Are you on the run in the mountains, but with lots of water available? In that situation, any good dehydrated or freeze-dried meals will work . . . for a week or so. If water is limited, there is no point in carrying the water plus the freeze-dried food instead of some less expensive form of preservation. What situation is this food for?
For sheltering in place, at home, you cannot beat the LDS Church https://providentliving.churchofjesuschrist.org/self-reliance/food-storage/home-storage-center-locations-map?lang=eng . Their food is good, nutritious, lasts for decades, and reasonably priced. I have a 2-year supply of their stuff, mostly with a 30-year shelf life, plus I have other items as a supplement for variety and flavor.
Those seem to be really great prices!
We’ve purchased Wise food, but if I had known about the Mormon food, I might have bought from them.
