Roasted Potatoes and Sweet Potatoes

This was kind of a fun recipe because if you use white-fleshed sweet potatoes you're never quite sure what you're biting into. And it's delicious. This would work equally well with yams (orange or purple-fleshed). It was savory, but also with a hint of sweetness. An easy, excellent side dish.
