Dice the squash into about one inch pieces. Toss in olive oil, rosemary and coriander. When I cooked it, it was for about 45 minutes in a 350 degree oven (I made it with the turkey below). going forward I would have increased the temperature to 400 and cooked for about 30 - 4o minutes. You can use butter in addition to or as a substitute for the olive oil for a slightly richer taste. Also, a sprinkle of salt could enhance the vegetables.
