A BIT PRICEY, BUT O! so worth it.
Occasionally, and despite my usual decent breakfast (homebaked bran-ginger-date-pecan muffin, high-protein yogurt, and coffee), I am apt to suffer hypoglycemia while perambulating about Sonoma. (There was even the time a few months ago when I approached some firefighter trainees to ask for a therapeutic granola bar and wound up riding an ambulance back to my house. Great story, too little time/space to tell it further.)
As proof against these attacks, I used to carry pitted dates in my EDC for gobbling to raise my blood-sugar. However, I recently hit on the following mixture which, in addition to being tasty, serves its purpose more admirably because of added protein:
Blend equal parts (say, at least a half-cup each) whole candied pecans, chopped candied pecans, chopped dates, roasted and salted pistachio kernels, dried cranberries, and goji berries. Portion out into a plastic sandwich or snack-size bag, seal, and tuck into EDC. (Try hard not to nibble on it unless needed.)
