What a flavorful salad green! Arugula has a peppery taste and is often used in salads as the main green or mixed with lettuce to balance the strong flavor. Pests, especially the flea battle, love arugula so we have to grow it under protective row cover or else it would come to you full of holes. If you find arugula is too peppery for you, you can mellow the flavor by wilting it either with a hot dressing or by throwing it in the pan in the last 2 minutes of cooking.
