>> Here's a different paradigm: Use the spiffiest whole-grain, organic, macro-biotic, dolphin-safe oats you want and. . . . bake oatmeal cookies. At home. Put in raisins/craisins if you want some fruit to, er, "keep you regular". Sweeten as much or as little as you like (honey, brown sugar, white, maple syrup, whatever).
On a scale of 1 to duh, this just pegged my duh-meter! As in, "why didn't I think of that"?! There's nothing in the oatmeal cookies I wouldn't put in my oatmeal in the morning. I do enjoy the hot oats on cold morning, but half of my backpacking is done when it's reasonably hot out, and I find I usually skip the hot oats on those mornings. This might be just about the perfect solution!
