1Preheat oven to 350degrees. Cut each squash in halve and remove the seeds. Place the 4 halves in a baking dish cut side down.
2Combine 1/4 cup of the melted butter and the brown sugar in a small bowl and mix well.
3In a separate bowl, combine the remaining melted butter, chopped apples, orange peel, raisins, nutmeg and cinnamon. Stir to blend.
4Remove the squash from the oven and turn cut side up. Prick the surface with a fork and then brush with the butter/brown sugar mixture, pouring any extra mixture into the halves. Fill each halve with equal amounts of the apple mixture.
5Place the filled squash halves in the oven and bake for an additional 30 minutes or until the apples are tender and brown.
