I have repackaged commercial freeze dried in zip locks and had no problem with them. I would rehydrate in a pot to avoid the mess in the bag. Dog cleans the pot, just needs a quick wash afterwards,
I now make almost all my meals and dehydrate. Even though there are some very tasty and healthier meals out there, I save money and have greater variety making my own, I will make extra of a one pot meal and dry the leftovers and vacuum seal. Yummy and fewer preservatives. I still may take one or two prepared for a quicker alternative. Good – to – go and Backpackers Bistro make some good alternatives and there is a new company, Trailtopia that sounds good but I haven’t tried.
