(Brassica rapa subsp. narinosa). Tatsoi is nicknamed Vitamin Green, and rightfully so. This gourmet green is known as one of the richest sources of vitamin C and it is replete with other incredible vitamins, minerals, and health-promoting compounds! Tatsoi also boasts glucosinolates (which have been extensively studied for their potential to lower the risk of some cancers) and carotenoids, which promote eye health. You won’t have to bargain with your kids to get them to eat this veggie. It’s super sweet and easy to love, with a mild and refreshing flavor. The low-growing rosettes are comprised of tiny, glossy spoon-shaped leaves that boast a crisp and juicy mouthfeel.
