Yams or sweet potatoes, peeled and cubed
Potatoes, peeled (optional) and cubed
Beets, peeled and cubed
Carrots, peeled and cubed
2 tablespoons olive oil
Peel and cut vegetables in uniformly sized pieces (the beets should maybe be cut a bit smaller since they are slower to cook). Toss in a bowl with the olive oil, rosemary and salt. Pour into a greased baking dish. Roast at 450 degrees for about 30 to 40 minutes. Sprinkle with balsamic vinegar, if desired.
