Blend in half of the bread crumbs. Divide filling evenly and stiff into the two eggplant shells. Place 1/2 cup water in a 12x8x2-inch baking dish; add stuffed eggplant. Cover and microwave on HIGH for 5 to 7 minutes. Rotate dish after 3 minutes. Top with remaining bread crumbs and paprika. Microwave on HIGH for 1 to 2 minutes longer.
