Favorite healthy to-go breakfast?
I take an early, 2-hour train ride to an internship two days a week. I like to get out of the house quickly, so most mornings I'm just making tea to go and then grabbing something that I've made in advance to eat on the train. I've tried to make things like toast that I can wrap in parchment paper or oatmeal-blueberry muffins, but I'd love more ideas! What's a breakfast you can grab quickly and run out the door (the less prep the better) that's also good for you?
