I dehydrate all my backpacking meals and use a nifty 10 tray TSM machine.

My basic premise is to prepare meals at home you really like to eat---refried beans, chilis, brown rice, grains, spaghetti, soups, baked sweet potatoes ETC and don't eat these meals but dry them for your trip. Most anything you like to eat as a meal at home can be dehydrated. Exceptions---pizza, ice cream etc.

Your next option is to buy canned foods you like---soups and whatever---and dry them.

Check out my Kitchen keyword pics which show several pics of stuff I've dried---
