I'm leaving later this week on a 4 day backpacking trip. I'd like to eat as primally as possible on this trip, but most of the foods I'm used to taking backpacking are definitely not in that category - pasta, peanut butter & crackers, super high carb dehydrated meals, etc. I'm currently making some biltong (mmm...) and will bring a dried fruit and nut trail mix for snacking. I'll probably also have some tuna and chicken pouches. Any other ideas for primal foods/meals that are lightweight and don't need refrigeration, but calorie dense enough to support hiking 7-10 miles a day with packs?
