What do you eat for breakfast?

Plain and simple...what's a breakfast you have success with? Keeps you at bay from cravings, helps you stay in your deficit, well-balanced?

My breakfasts consist heavily of fruit/greek yogurt, but I've started to incorporate these things into my lunch, and I'd like to not eat the same thing for two meals in a row. I don't love eggs, but can get down with them from time to time. I'm needing some ideas though!!! Bonus points if it's manageable to eat on the go, or at least bring to work to eat later (it's so hard for me to eat right when I awaken).
