I found this post on the blog Wandering the Wild, which gives ideas on camping food. This post is geared toward hikers but is also helpful for overlanders interested in no-nonsense provisioning. I like the way they pack everything in space-saving Zip-loc bags as well.
I’ve found dried soups (just add water and heat), canned goods, and single-serving, shelf-stable milk very handy for simple cooking on the trail. Except for cold beers, it’s not that difficult to travel without a cooler.
