Tina’s Tidbits:
Tossing barley with a small amount of oil will prevent the grain from absorbing all the moisture from the dressing
For a more robust color, add diced red bell peppers or small, halved, cherry tomatoes to the barley mixture before adding the dressing
Blanching vegetables for a short period of time brings out the natural sweetness and color as well as slightly softening the food
