I throw some frozen berries in a cup the night before and stick it in the fridge. By morning it's mostly melted, and makes for a nice breakfast smoothie that doesn't give you brain freeze by adding milk and bananas (and protein powder if you like the stuff). When I get to work I inhale a small cup of yogurt.
Honestly I'd rather have the yogurt in the morning and the smoothie when I get to work, but bringing that stuff to work would be a chore in itself.
