Don't freeze dry, but I dehydrate all of my backpacking meals in an inexpensive, run of the mill dehydrator. House and other freeze dried meals don't agree with me. I stick to basic, healthy recipes and do very well with energy levels. I usually just pick one or two recipes and make pounds and pounds of it for the season. It can be boring to eat the same thing over and over again, but I find that for me anything hot at the end of the day is good. I found some thick food grade bags on amazon that stand up on their own and seal well, so I can cook right in the bag. When you're done eating, seal it up and toss it in your food bag. Nothing to clean up. Most of my recipes turn 16-18oz of "wet" food, into 3-4 oz dried. There is a ton of good info on this if you venture onto serious backpacking/though hiking websites. There are a lot of tips and tricks to get things to dry and reconstitute better.
