Los Rios Apple Crisp

Preheat oven to 350. In 9-inch square baking dish or round pie plate mix apples with granulated sugar, 2T flour and cinnamon. In a bowl combine rolled oats, brown sugar, 3/4 cup flour and margarine cut into 1/2-inch chunks. Rub with fingers until butter pieces are absorbed. Stir in nuts gentle and sprinkle topping over apples. Bake in oven until apple are tender when pierced and topping is browned, 45 minutes to an hour. Cover topping with tin foil if it browns too quickly. Serve slightly warm or cool with optional scoop of vanilla ice cream.
