Easy way to dress up plain winter squash.  Our friend described this as "Kinda like mashed potatoes, except way better!"

3 eggs, lightly beaten
¼ teaspoon nutmeg
Salt and pepper to taste
2-4 tablespoons melted butter

Half and seed squash, place face down in baking dish in 1 inch water.  Bake at 400 until tender.  Cool.  Puree all ingredients.  Put in baking dish.  Bake at 350 for about 30 minutes.
