If you define breakfast as a meal consumed in the morning, then I don't eat at anything at all. I prefer to go to the gym on an empty stomach and eat around noon.
If you define breakfast as the first meal of the day (whenever that is), then here's an example from today:
1 serving of carrots
1 serving of spinach
dextrose (only if I worked out that morning)
1 scoop of protein
1/4 pound of oatmeal
1 banana
2 bagels (plain, usually. Also only if I worked out that morning)
Lots of water
...then I move onto less carb-y things later in the day.
