Mashed Butternut Squash
Line an oven-safe pan of appropriate size with foil and put squash in it. Bake at 350 °F for about an hour until the squash is soft.
Allow it to cool, then cut open, scoop out and discard seeds, scoop the inner flesh (squash) from the outside skin, and mash the squash.
Top as desired with margarine and a sweetener of choice.
