The easiest way to cook the acorn squash is to cut it in half, place it in a baking pan, cut side down, add about an inch of water to the pan and either microwave it (approx. 10 - 15 minutes) on high or bake it at 350 until it's soft.
Optional Step, when flesh soft enough to pierce with fork, turn over each half, sprinkle flesh with Truvia and bake another 15 minutes.
Note from Leslie: I liked it with Walden Farm's pancake syrup and cinnamon. Kind of like a sweet potato.
