2 large apples, cored and cut in 1 inch chunks
2 large sweet potatoes, peeled and cut in 1 inch chunks
1/2 cup brown sugar
1/2 cup oat-bran cereal, milled to flour in blender or food processor
1/2 cup 1-minute oatmeal
1/2 tsp. cinnamon
1/3 cup unsalted soft butter

Mix the chunks of apples and potatoes in a 9 inch pie pan, and sprinkle with 2 tablespoons of the sugar. Mix the remaining sugar, oat bran, oatmeal, and cinnamon in a bowl. Work the butter in a bit at a time until the mixture is crumbly. Sprinkle the crumbs over the apples and potatoes. Preheat the oven to 350°F.

Bake about 50 minutes, or until the potatoes are tender and the topping is browned. Serve when still warm.

For a special treat, beat chilled evaporated skim milk with a teaspoon of vanilla to form a "whipped cream" topping.
