It’s not as much of a stretch to add them to your life as you might think. It’s as simple as tossing a handful of chopped greens into a tomato sauce or soup, adding a few leaves to your usual smoothie (they won’t change the taste of it) or adding a handful to a saute or stir-fry. There’s a bounty to choose from, such as arugula, spinach, Swiss chard, kale, collards, mustard greens and beet greens.
