I'm guessing the yellow stuff is grits.
I have found that oatmeal is a great morning breakfast. Good carbs, good fiber and some added protein. And I find it to be long lasting. A little fruit like blueberries added in along with some coffee and I'm ready to go. And I take som Gu with me on the ride. I try not to pull out the Gu until very late in the ride when I am most likely to have depleted most of my energy stores. Although given what I have around my waist, I have a long way to go to use up my energy stores.
