Preheat the oven to 350 degrees. Peel and slice the Squash into thin, Lasagna like slices. The original recipe suggested using a Mandolin to keep the slices of uniform thickness, but I'd recommend just slicing it as close to uniform as possible. Place the squash slices in an 8 oz square microwave safe glass baking dish, and microwave the squash slices for 4 minutes, covered with Saran Wrap. Remove the squash slices, and spray the glass dish with Cooking Spray.
