Remove twelve large leaves of cabbage, cut out tough inner part of rib. Blanch each leaf one minute, until pliable. Combine ground turkey, rice, egg, stock, sage, and parsley. Add salt and pepper to taste. Divide turkey mixture into twelve parts, and form into four inch ovals. Place an oval at stem end of cabbage leaf, fold in sides, and roll up. Place roll in shallow baking dish. Continue until all twelve rolls are in one layer in baking dish. Pour 1/2 cup stock over all. Lay strips of bacon on top. Bake at 375 degrees for 30 minutes, basting twice, and turning oven temperature down to 350 if bacon browns too quickly.
