You can pay $3 for a bunch of watercress—an antioxidant powerhouse—at your local grocery store…or you can find a stream and stock up for free. An increasingly popular ingredient in gourmet salads, many people don't realize that watercress is actually a weed. It grows alongside streams and riverbanks in nearly every U.S. state. The most popular way to eat watercress is to add it to salads raw. If you need some ideas, check out the watercress recipes in the Rodale Recipe Finder.
