1 1/2 tablespoons margarine
2 teaspoons cinnamon
1 1/2 cups old fashioned rolled oats
2 apples, peeled, cored, and chopped
3/4 cup dried cranberries, raisins, or other berries
3/4 cup chopped walnuts or pecans

Preheat oven to 350ºF.

Combine milk, brown sugar, margarine and cinnamon in a saucepan. Cook, stirring frequently, until it comes to a boil. Remove from heat.

In a mixing bowl, combine the oats, apple, cranberries, and nuts. Add the hot milk mixture and stir well to combine.

Spray a 9×9 square baking dish with cooking spray. Pour oatmeal into the baking dish and bake in a 350º oven for 30 minutes.

Serve immediately, or refrigerate and heat up individual portions in the microwave.
