What is it? Rainbow chard or Swiss chard are green leafy vegetables with leaf stalks that can be white, red, yellow or red and white.
What it tastes like: Young chard is mild and tender; more mature chard may have an earthy, slightly bitter flavor.
When you can find it: Late fall and winter.
How to store: Refrigerate unwashed in a plastic bag and store in the fridge.
