A great way to incorporate more vegetables into your diet is to try new recipes by trying new foods. Rutabagas are an interesting, different root vegetable (known in some places as turnips) that can be used in a variety of ways - roasted, baked, broiled, boiled, stewed, etc. In Scotland, they are known as "neeps" and made in a dish called "neeps and tatties" where tatties are potatoes.
Here are a few recipes to try:
Rutabaga Hash With Onions and Crisp Bacon
Roasted Rutabaga
Rutabaga Oven Fries
Scandinavian Rutabaga Ham (Griljerad Kålrot)
