Rainbow chard is a mix of Swiss chard, red chard, and golden chard. Use it as you would any other chard, but be ware that bunches that contain red chard will bleed just as red chard does and stain lighter vegetables pink. As with all chard, you can remove the center ribs for seprate cooking, if you like.
