One thing I always bring with me if I am going to carry food is Pita bread. I do not have to worry about it getting squashed. Actually any flat bread if good.
If you find you are being too picky about camp sites, wait until you are too tierd or it is too dark and then you may not bee so picky.
Always hang your food in trees if there is the remotest possibilty of bears in the area, and especially if is raining. Animals tend to have a keener sense of smell when it rains.
