In a saucepan cook celery and onion in butter or margarine till tender but not brown. Remove from heat; stir in poultry seasoning or sage, salt, and pepper. Place the dry bread cubes in a large mixing bowl. Add the celery mixture. Drizzle with enough broth or water to moisten, tossing lightly. Use to stuff one 10-pound turkey. Serves 10 to 12.
