15. Watercress

This lovely green grows wild on the edges of streams; it’s one of spring’s first leafy greens to emerge. It is characterized by its small glossy round leaves and almost succulent-like stems; not to mention its wonderfully peppery taste. Watercress is an excellent source of vitamins A and C; and a study in the American Journal of Clinical Nutrition found that eating just three ounces a day boosts your levels of certain antioxidants by 100 percent. 

It is delicious raw in salads, but can also be sautéed, or used to make watercress soup, among other uses.
