Grab a few of those prefrozen chicken breasts and put them in a Ziploc bag with the following ingredients.
2 cups sour cream
1 envelope ranch salad dressing mix
4 teaspoons lemon juice
4 teaspoons Worcestershire sauce
2 teaspoons celery salt
2 teaspoons paprika
1 teaspoon garlic salt
1 teaspoon pepper
6 boneless skinless chicken breast halves (6 ounces each)
1/4 cup butter, melted
Combine the first eight ingredients in a large resealable plastic bag; add chicken. Seal bag and turn to coat; refrigerate for 8 hours or overnight.
Drain and discard marinade. Place chicken in a greased 15x10x1-in. baking pan. Drizzle with butter. Bake, uncovered, at 350° for 25-30 minutes or until juices run clear.
