I'm not very fond of trail mix, and most for me are too salty. Even while backpacking, I end up retaining fluid if I eat a lot of salt. Also, I long ago got used to eating a diet low in salt and learned to dislike salty foods (that dates back to my childbearing days when I basically couldn't eat salt during pregnancy).

I buy nuts, mostly unsalted, in bulk in the Fred Meyer health food section, and dump a little of each kind (almonds, walnuts, cashews, peanuts, hazelnuts) in a sandwich bag and add dried fruit for each day's snack/lunch. On a long trip (more than 7 days), the fruit will be freeze-dried, to save weight.
