I do about the same as Blast. I try to carry some Hickory Farms Beef Stick, especially the little bite sized party links. I also like cheese for lunch but when the weather is hot it is tougher to carry.
Nuts are excellent, dried fruits, raisins, Wheat Thins anything edible, won't spoil quickly and good for me!
I sure agree about the freeze-dried meals, a few are acceptable but most are tough for me to choke down.
I have taken pre-cooked bacon, fresh eggs and orange juice for breakfast before, first day only deal.
A great surprise dinner is a nearly fully cooked filet mignon, some boil in the bag rice, a vegtable and store it in a soft cooler with some blue ice. You need a fire and small grill to finish cooking the steak and warming the other things, but it sure tastes good! I freeze all that before the trip, carry it in the soft cooler and by evening it is ready for the fire.
Cheers!
