It takes some experimenting. For me, no matter how much I cut back, it seems that I end up with leftover dinner that I can't eat. Unfortunately, for a long timne the reconstituted food that I couldn't eat was just as heavy as the home-dried dinner that I started with, so that unless I was where I can build a fire (rarely), I packed out almost as much garbage as I carried food in. It's just that the dinners look so tiny in their dried state! Finally I'm getting to where I can avoid dinner garbage. I'm actually best off not to take more than a pound of food per day. I snack on nuts, cereal bars and dried fruit all day, which is undoubtedly why I don't have much appetite for dinner.

And no, I can't give the leftovers to my dog because he has all sorts of allergies, including to every grain except rice.
