Arugula is one of the healthy, vitamin-rich herbs. It has been known since the time of Julius Caesar, and then they called it mustard grass. It does taste a little bitter, but its spicy, pungent taste goes well with other vegetables in salads. Only the young leaves of this plant are suitable for food. They are sold in small packages in supermarkets throughout the year. Having purchased such packaging, the greens must be used within several days, otherwise they will lose their beneficial properties.
