Pumpkins: you've probably picked them, carved them and decorated your home with them, but have you cooked one for dinner yet? It may be time to give it a try.

This autumn squash mixes well in more than just pumpkin pie and pumpkin bread. In pastas, stews, and even on pizzas, pumpkins are a versatile ingredient that can be added for just 30 calories in one cup.

And not only will you get some fall flavor by cooking with this squash, but you'll get many health benefits as well! Pumpkins are rich in Vitamin A, fiber and potassium. In just one cup, you'll get 200 percent of your daily Vitamin A intake, which promotes healthy vision, and a rich amount of antioxidants called carotenoids. Even the seeds have their own nutritional benefits; they contain magnesium, copper and zinc, among other nutrients.
