In search of the perfect breakfast

Here's my criteria for the perfect breakfast:

Can prepare and eat in under 15 minutes
Healthy
Not too expensive
I make it until at least 8 AM until I'm hungry again.


I think my metabolism must be much higher in the morning, because I can go hours and hours in the evening without even thinking about dinner, but every morning is a struggle to make it through work without stopping by the vending machine. (I stopped bringing money with me, but there is an ATM if I get really desperate) Maybe it's the bordom factor also, or just mentally used to sitting at my desk and eating.
I eat breakfast at 3:30 and am finished with work at 9. If I'm hungry when I get home, I can still make it to lunch, but sitting at my desk I can barely stand it 5 minutes.


I have found that the closest thing to a perfect breakfast is homemade granola cereal with soy milk, and then bring a piece of fruit as a snack.
But somedays you just don't feel like granola, and that leftover Pad Thai looks so yummy. And then you're hungry in an hour so you eat your snack which is much smaller than you thought. And then you find out that one of your coworkers is sick and you have to stay late and you have no food and you just waste away in your cubicle and they find you the next day with a half eaten pad of paper next to your skeletal corpse.

Ok. Heh.

Well, what do you eat for breakfast?
