Preheat oven to 350. Place fruit in the bottom of a 9-inch square baking pan and sprinkle sugar over fruit. In a medium bowl blend together the margarine, flour, brown sugar and oats, until it resembles a coarse meal. Sprinkle over the fruit. Bake for 30 minutes or until lightly browned. Serve hot. VARIATION: May use other berries or fruit of your choice.
