Giada's Roasted Potatoes

I love roasting these tiny peewee potatoes (sometimes you'll see them labeled with different names - but basically, any waxy potatoes that are really small!).  They couldn't be simpler to throw together, and they really make a delicious crowd-pleasing side dish. Sometimes we think of potatoes as an unhealthy food, but when they're prepared this way - with just a bit of olive oil, seasoning and an onion thrown in - it makes for a great health-friendly side dish.
