Today I had a 2-pound Porterhouse, but only because I had it on hand and I was goddamn starving.
I usually eat leftovers from whatever I've cooked the day or night before, which is often meat and vegetables of some kind, or pizza. If I have the time, I'll whip up an omelette or a tuna or peanut butter sandwich.
Oatmeal, if I have it, which I eat with some kind of fruit and/or honey. The usual morning drink is copious amounts of water—a litre and a half on average in the first hour of waking if I can manage. I'll make tea or coffee if I have time to enjoy it.
My logic behind breakfast is simply this: No matter how wild it might be, I try to get hot protein and carbs in me as soon as possible. I always have the best luck with hot foods and liquids in the morning: they get the ol' internal bonfire stoked faster and hotter than most anything else I eat in the morning. Cereal is right out.
Hot, high-protein/carbohydrate, low-fat/sugar foods are a kick in the ass in the mornings.
