How to Make It
Preheat oven to 400°.
Combine first 9 ingredients in a large bowl; toss well to coat. Spoon apple mixture into a 13 x 9-inch baking dish coated with cooking spray.
Place oats in a food processor, and pulse until coarsely ground. Add flour, 1/4 cup sugar, and margarine; pulse 10 times or until mixture resembles coarse meal. Sprinkle over apple mixture.
Cover mixture, and bake at 400° for 30 minutes. Uncover, and bake 20 minutes or until the fruit is tender and the topping is crisp. Serve warm or at room temperature.
