For those looking to travel light and fast (i.e. no cooking), has anyone tried to use freeze dried food by adding water and waiting (maybe 30 minutes?) and then eating on the trail? I have never tried it but heard a rumor that it works OK, though obviously it's not warm food.
Yep, I've done this--and it mostly works. Some things hydrate better than others, but everything seems to hydrate well enough to be eaten. Just drink a little extra water, and you'll be fine!
