I'm not a big fan of pre-ride eating, especially in the morning. However, you can't go wrong - brain glucose levels are most likely lacking. This can be made up by cortisol and glucagon acting on glycolysis pathways in response to riding/work/etc, but it's never a good idea to ride in traffic with the morning fog sitting in the brain.

If you want something quick, easy, and also with high water content, then mix up a quick nutritional shake before the ride. My 3-month-old has been keeping me up to 1-3am lately, which means I'm too tired to make up a pre-ride meal, so I mix up some non-fractionated, fortified soy protein with a shot of green superfood powder (enzymes, baby!). I've also been grabbing a piece of fruit on the way out the door, for when I arrive on campus. Can't go wrong there!
