I don't like most freeze dried foods. For 2-3 day hunts, I'd do wheat toast, heavy dose of peanut butter, bacon cooked extra chrispy, and honey sandwiches. The calorie, fat, protein loads of those are very nice and I actually look forward to eating them. That along with trail mix and a variety of snack foods last 2-3 days easy. Plus no need to pack a heat source.
