What I did was pick up some Lite'N'Fit snack size yogurt cups. I know we aren't supposed to do the fruit flavors during P1, but I can't stand plain yogurt, and, like you, don't have a lot of time in the mornings. The yogurt has 40 cals, 0 fat, and is sweetened with Splenda.
They were (and are still) perfect for me. I'll either grab one and eat it when I'm getting ready, or if I'm really short on time, I'll just throw it in my lunch, and eat it at work.
For me, it's just the right size at 4oz. because I'm lactose intolerant, and any more dairy would not be a good thing - at least for my co-workers.
I've also eaten celery and hummus for breakfast when I forget to pick up more yogurt, or even lf string cheese.
I'm pretty boring when it comes to creative breakfasts - this is the 1st time in close to 20 years that I've eaten breakfast more than two or three times a month, so I'm not a huge help - sorry.
