We are going in Aug this year and doing all our own food. Look at
(You need to Login or Register to view media files and links)They have some really good recipes for dehydrated meals and we're having a blast testing them out. Basically if it is something you like to eat at home you may be able to modify it to the point where you can do "freezer bag" style cooking.
We have the American Harvest food dehydrator and love it. We just need more trays.
In a nutshell it's a meal that has been dehydrated (or the ingredients will be cooked) when you add boiling water to the contents in a freezer bag and let things steep for 5-15 minutes. Viola - meal in a "pot" so to speak. No messy clean up, rinse out the freezer bag after eating, put it in your garbage to pack out and you basically clean your spoon/fork. Enjoy the rest of your evening in front of the fire.
Many of the recipes use a foil packaged chicken/beef (or shrimp - yum) which is shelf stable and this way you have real meat not dehydrated chunks which can be chewy. Other than turkey burger we have not yet tried to do meat in the freezer bag type cooking. Turkey burger worked remarkably well, far better than I thought it would.
We've only done a couple experiments so far but I will never go back to pre-packaged freeze dried stuff now that I know I can take my wife's awesome cooking into the BW.
And it's remarkably easy to do with a dehydrator.
