Beet and Sweet Potato Gratin

A colorful side dish. Try a variety of beets or mix in other root vegetables to enhance the rainbow effect! A mandoline will make short work of the slicing, but otherwise take your time and make the slices between 1/8 and 1/4 inch wide. The dish can stand for a long time before serving so it's a good choice for making ahead if necessary. Reheat in a 350 degree oven for 15 minutes if needed.
