This super-duper-easy recipe brings together a few of my favorite things, namely tender chicken, sweet veggies, good-for-you barley...and my beloved slow cooker. It's one of those recipes that is so ridiculously easy that it feels like magic when you toss everything in and it comes out of the slow cooker as a perfect concoction of warm and wonderful soup. It's the perfect thing for chilly, busy winter days.
