Place the bottom of the rolls inside a lightly greased 13x9-inch baking dish. First layer with bacon, then sprinkle with the shredded cheese.
Toss the cooked chicken with the ranch dressing and heat in the microwave for 2 minutes, stirring halfway through. Top the cheese with the warm chicken and ranch. (Warming the chicken first cuts down on bake time and ensures safe food temperatures.)
Place the top half of the rolls on top of the chicken layer. Combine the butter, garlic, parsley, and salt. Spoon or brush over the tops of the rolls.
Cover with foil and bake at 350 degrees Fahrenheit for 25-30 minutes or until heated through (165˚F) and bubbling in the center. (If using cold chicken and ranch, this could take up to 1 hour.) Serve hot. Enjoy!
