Preheat oven to 375°F.

Combine 2 teaspoons granulated sugar and cornstarch in medium bowl. Add berries; toss to coat evenly. Divide berry mixture between 2 (5-inch) heart-shaped pie plates or 5-inch baking dishes.

For topping, combine oats, brown sugar, flour, remaining 1 tablespoon granulated sugar, cinnamon, ginger and salt in small bowl. Cut in butter using pastry blender or two knives, then mix with fork until mixture resembles coarse crumbs. Sprinkle topping evenly over berries. Bake 20 to 25 minutes or until topping is golden brown and berries are bubbling around edges. Serve warm with vanilla ice cream, if desired.
