Swiss Chard
In the world of hearty greens, Swiss chard often gets overshadowed by its popular neighbor kale, but it’s a superstar in its own right. This relative of the beet is a superb source of vitamins A, C, and K, as well as magnesium, potassium, and iron. It makes a colorful and tasty side dish, or a nutritious addition to pasta, soup, quiches, and more.
