I typically split breakfast into two "meals."
The first is usually a blended smoothie of non-dairy milk, protein powder, oatmeal, yogurt, fruit (often blueberries) and just a little bit of black coffee to get something into my system before the gym.
Later, after the gym, I eat something more solid. What exactly the "more solid" thing is varies, but some sort of egg is usually involved. I'll likely have a small piece of wheat toast on the side. If I'm in a hurry, I might settle for breakfast cereal of some sort.
