I can't imagine having softdrink (soda/pop) for breakfast.
Maybe a donut with a coffee? I don't think I'd call it the breakfast of champions though. lol
I suppose I think of a champion breakfast as something healthy which will give you energy. Of course, that means I don't think nutrigrain fits the bill either.
I'd go for a good quality muselie(sp?) with some yoghurt and fruit on top. Now that's a breakfast of champions.
Oats are good too...specially when you pop to dried fruit in at the start of the cooking process so it plumps up nicely. yummo!
