Most of my trail breakfasts are granola with dried blueberries, currants, and any berries I can find in the wild.  Added to that is a mix of 1/2 Carnation instant nonfat dry milk and 1/2 Nido (powdered whole milk), which yields 2%.  Because the Nido is slow to dissolve, I mix it up ahead of time as Bill Conner does, and by morning it's ready. 

Outdoor Herbivore has a few nice quick breakfasts, too.

If it's chilly and I have a little extra time I heat the milk for a wonderfully warm start to the day.
