It has to be eggs! They make breakfast worth eating - if I eat anything else then I'm hungry in a couple of hours anyway. You can do sooo much with them! Scrambled eggses are my favourite (especially when they're loaded with pepper), with soft boiled (and toast soldiers!) and poached as close seconds.
I go through phases about what I like to eat for breakfast. Right now I'm in a cinnamon bread with butter stage - I've gone through a cereal stage, a bagel stage, a peanut butter & crackers stage, and a waffles stage. Basically, I eat something every day for breakfast until I get sick of it, and then I start eating something else. My favorite breakfast food of all time would have to be french toast, but I rarely ever get to have it. I usually have to make my own breakfast in the morning, and there's no way I'd be able to make myself french toast without it turning out bad.
During the school year I'll usually have cereal if anything(often don't have time in the morning). During the summer when I'm at home I'm rarely up before noon so I just wait til lunch. At camp I got in the habit of having hot cocoa and muffins every day(along with the occasional bacon or potato pancakes). Mmm, muffins. And cocoa
