I frequently make spiced nuts--almonds are pretty good vehicles for hot/sweet spice combos. There is almost always a granola bar from previous flt (or airport lounge) somewhere in the bottom of my backpack. Boss likes plums because he eats the hard as rock ones as well as my nutty creations. For short flts, I go for the peanut or pretzels.
Smoked almonds are pretty hard to beat at any time!
