Romaine has a mild, sweet flavor and a hydrating crunch. Best known for the classic Caesar salad. Wonderful on sandwiches and burgers. Romaine is low in calories and a great source of Vitamin A, Vitamin K, and Folate. Store lettuce in a plastic bag, in the refrigerator. Best eaten within a few days but will keep for longer, up to a week. Please note that we typically don’t wash the salad greens we pack for you unless they’re very dirty, because they store better unwashed. If you choose to wash your salad greens, invest in a salad spinner so you can be sure to get them truly dry.
