Preheat oven to 450 degrees. Prepare pastry as directed except roll 1 inch larger than 12 or 13 inch pizza pan. Ease into pizza pan; flute edge. Cut apples into slices 1/2 inch thick (about 8 cups). Beginning at edge of crust and overlapping slices, cover crust with apples. Stir together sugar, cinnamon and nutmeg; sprinkle over apple slices. Top with crumble topping.
Bake 30 to 40 minutes or until edge is golden brown and applesauce tender. Best served warm and if desired topped with ice cream.
Mix 3/4 cup all purpose flour, 1/2 cup sugar and 1/2 cup firm butter until crumbly.
