first thing after I wake up, get a pot of green tea going, and then some cut up fruit
(fresh pineapple is my weakness, plus banana, apple, mango, whatever happens to be in the larder) to get the system "cleared out."

Ideal is steel cut oats cooked with a dollop of peanut butter at the bottom of the bowl, raisins, brown sugar/molasses and milk. Yum! That is the touring breakfast of champs. I've met more bike tourists that eat that combo everyday. sticks to the ribs.
plus some water
