1 Preheat oven to 375 degrees F (190 degrees C).
2 In a medium bowl, mix together the oats, brown sugar, flour, and cinnamon. Stir in the melted shortening and water to form a crumbly mixture.
3 In a large saucepan, mix together the cranberry sauce and cornstarch. Bring to a boil, and then remove from heat. Stir in the apples. Spread into an 8x8 inch glass baking dish. Crumble the oat mixture over the apples.
4 Bake in the preheated oven for 30 to 35 minutes, or until the apples are tender. Serve warm.
