Make a bunch of granola. It's light, needs no preparation so you can munch it dry on the trail, keeps well, tastes good and is healthy. Bean salad is good too for many of the same reasons. They seem to keep their crispness best when winter camping. Store bought tortellinis aren't too bad either.
Any flat bread is great to pack.
My favorite is Pita bread. Also, if you have never tried making bread in camp, you are missing at least half of the food fun. It takes no trouble at all to make biscuits. Very little trouble to make rolls of some sort. Virtually painless to make real bread.
