Butternut Squash with Apples

Cut squash in half, lengthwise. Remove the seeds and fiber with a spoon. Arrange in a 13x9x2 baking pan. Peel and dice a granny smith apple. Place the apple in the hole where the seeds used to be. Mix butter, brown sugar, flour and salt and sprinkle over the top of the apples and squash. Add water to the bottom about 1/4 full. Cover the pan with foil and bake at 400 for 30-40 minutes or until tender.
