Ongoing argument whether this is a side or a dessert, Great as both, depends what you're looking for.
1 (14 oz) can cranberry sauce
1 cup flour
1 cup oats
½ cup margarine or oil
¾ cup brown sugar
¼ tsp cinnamon
Mix the cranberries and sliced apples together. Lay flat in a pan (I like to use a glass dish so I can serve it as is).
Combine the topping ingredients. Pour on fruit and bake at 350℉ for 1/2 hour.
