Kohlrabi is a good-for-you cruciferous vegetable low in calories and high in antioxidants and fiber that is a popular go-to side dish in hungary, lithuania, poland, russia, and ukraine. When stuffed, as in this hungarian stuffed cabbage recipe (tlttt karalb), it's reminiscent of stuffed cabbage rolls. Ground beef or a combination of beef and pork, or beef, veal, pork, and lamb, or any combination thereof can be used, and leftover cooked ground meats work as well. Kohlrabi can be used for a totally vegetarian dish by stuffing it with well-seasoned grains like millet, barley, buckwheat groats, rice, sauted onions, and mushrooms, or whatever whim strikes you.
