We do have a bakcountry cooking/food forum here, Lite Food Talk, with lots of ideas and recipes.

A great site is "Sarbar's" Trailcooking.com

Try a Clif bar or two before buying a bunch; I personally can't stand them. Your Mileage May Vary, of course. My favorites are Kashi Bars and Odwalla Bars. Again, YMMV!

Actually, it's a good idea to taste-test every food at home before the trip. That's especially true of home-dehydrated meals. The regulars here already know my story about the home-dehydrated tuna casserole in which the peas remained the consistency of buckshot after all the other ingredients were cooked to mush.

While I now avoid dehydrating peas, I do cook one-dish meals in large batches and dehydrate them for my backpacking meals. I personally can't stomach the salt and preservatives in Mountain House. I pick items that can be reconstituted with boiling water and kept warm in a cozy for 15 minutes or so.
