I created this dish in an effort to find something I can pack and bring to work for lunch that will keep me feeling full. Nothing undoes the hard work of eating a healthy diet quicker than a growling tummy. Studies have shown that barley contains dietary fiber that can slow glucose absorption and control blood sugar levels. I've used it as the base for the dish along with nutrient-packed veggies and lean protein. I suggest serving the salad at room temperature.
