Eating in the car is a sticky subject. If you love your ride, you don't want to get it messy. And with the dawning of 2012, we bet you've made some New Year's resolutions about getting a little healthier. Luckily, several healthy foods are also incredibly car-friendly. One thing before you start: get yourself one of those protein shaker bottles. They're airtight, and they have a big opening at the top, since protein drinks are usually thick. That makes them ideal for holding small, crunchy things like cereal, then pouring them into your mouth a little at a time while driving. Also, they usually fit your cup holders nicely. See? No sticky fingers, no mess, and snacking satisfaction.
