Red and Gold Beet Salad with Pistachios and Feta

Choose as many varieties of beets as you can find for a truly spectacular, colorful salad. We typically use a mixture of red beets and golden beets, but when we can also find pretty Chioggia (striped) beets, we throw them in as well. Make sure you roast the golden or striped beets separately from the red beets, which will color them red. (Red beets make a great natural Easter egg dye!)
