1. Arugula

Once only found in European markets, in the United States arugula has become a bit of a hallmark for highfalutin eating. It is easy to spot because of its small, flat jagged leaves with long stems and often strong, peppery taste; it is mostly used in salads but can be sautéd too. And consider this: Arugula contains roughly eight times the calcium, fives times the vitamins A, C and K, and four times the iron as the same amount of iceberg lettuce. If it’s too spicy for your taste, it can be blended with other salad greens to calm down the flavor.
