Ok here is the mix for granola that had the TSA stumped last summer on my trip to Seattle. They re-ran this stuff through the xray about 3 times before they decided it wasnt explosives.

Ok here goes the rather ad lib version of what to use. It is more an experiment each time but a very tasty one. Jennifer, my gf, usually starts with equal amounts of peanut butter, almond or cashew butter, honey and molassas. We make alot so 1 cup of each. Warm them together in a sauce pan so they are a bit liquid and will mix with the grains. Now the rest is really totally up to your taste. We dont use the carob or chocolate but stick with dried fruit and such. So in a big bowl put in raw oat(not the steel cut Irish teeth breakers), sun flower seeds, flax seed, chopped almonds or any other kind of nut you might like. Bits of dried fruit are really good in this too. Pour in the liquid mix from the sauce pan and get your hands into it mixing it all up. Press it into a pan and let it sit in the fridge a day. This stuff wont really set up into bars or anything so just break off a bunch and put it in zip locks and pack it with you. Ive had some in my car for 4 months and it hasnt gone bad at all. Mostly find a good natural food store with bulk grains and nuts and fresh ground peanut and cashew butter and use your imagination. Because of the complex carbs of the molassas and honey it kicks in with an energy boost that wont flash and crash you. The grains just keep the energy in you going.
