Also suggest the single serving size cans of fruits, vegetables, meat (yes Spam has a small size can), tuna, cheese whiz, ect.
They are easy to store under the bed, under the couch, and that way if you have a situation were you can’t get any water for cooking you will at least have something to eat.
A small closet can be made to store a surprising amount of food, even apartment dweller.
As it happens, made a freeze-dried meal last night, for the heck of it. Major label “beef stew”. Worse than I remembered from previous repasts. Yeah it’s edible, just barely. Let it soak for a half hour (ready in “ten minutes” means crunchy, half-reconstituted bits)
The meal would have benefited greatly from a half hour simmering, or maybe more - my impression was that the initial stew itself was not cooked thoroughly to begin with. It would be salvageable with a lot of extra cooking time, ingredients like onion and such, butter, broth.
Some freeze dried items are better than others, but I’m just not seeing the advantages unless one is planning on hiking or climbing. Canned goods are a lot cheaper and taste much better.
