In a small bowl, mix bread crumbs, Parmesan cheese, and paprika. Dip rolls in a mixture of beaten egg and the 1 tablespoon water. Coat with the bread crumb mixture. Place rolls, seam sides down, in a lightly greased 12x7x2-inch (2-quart rectangular) baking dish. Drizzle with the 2 tablespoons melted butter or margarine.
