1. Cut chicken into 3/4-inch wide strips; set aside. In a shallow bowl combine sour cream, lemon juice, Worcestershire sauce, paprika, celery salt, and pepper.
2. Dip chicken strips into sour cream mixture; coat with crushed stuffing mix. Arrange chicken strips in two large shallow baking pans (pieces shouldn't touch). Drizzle melted butter over chicken.
3. Bake, uncovered, in a 375 degree F oven about 25 minutes or until chicken is no longer pink, rotating pans after 15 minutes. Makes 10 to 12 servings.
