Preheat oven to 350°. In a large bowl, combine eggs, cream, milk, sugar and vanilla. Stir in blueberries. Combine mixture with bread cubs. Allow to stand 15 minutes or until bread is softened.
Transfer to a greased 13-in. x 9-in. baking dish. Bake, uncovered, 45-60 minutes or until a knife inserted near the center comes out clean. Let stand a few minutes before serving.
For sauce:
In a small saucepan, combine blueberries, sugar and water. Stir often and bring just to a boil over medium-high heat. Allow to cool slightly or serve at room temperature. Serve with bread pudding.
