It depends. When I'm at home, I'm a cereal hound. I LOVE the stuff. But when I go out, I usually like to get some awesome artery clogging breakfast.
My favorite is from a little restaurant in Olivet, MI. The meal is called the "Ernie Special".
2 eggs any style (mine are always sunny side up)
Toast
Giant pile of hash browns with cheese, onions, green peppers, and ham or bacon (I always go for ham, and they DON'T short you).
Such a good breakfast, though I always find myself needing a nap afterwards.
