PREHEAT oven to 350 F. Lightly spray an 8 inch square baking dish with butter-flavored cooking spray. Set aside.
PLACE all filling ingredients into a large bowl. Toss fruit gently. Transfer to prepared baking pan. In another bowl, place all topping ingredients except margarine. Stir to mix. With fingertips, squeeze margarine with flour mixture to form small, moist crumbs. Sprinkle topping evenly over fruit.
BAKE crisp until fruit is tender and topping is golden brown, about 45-55 minutes.
SERVE warm or at room temperature. Feel free to top with ice cream or whipped cream. Enjoy!!!
