Spray counter lightly with non-stick cooking spray. Combine rolls and roll into a 12x15-inch rectangle. Cover with sprayed plastic wrap and let rest.

In a large bowl, combine mayonnaise, parsley, mustard and onion. Stir in the chicken, bacon and cheese. Remove wrap and spread filling evenly over dough.

Starting with a short side, roll up tightly. Pinch edges to seal. Join ends to form a ring and place seam side down on a sprayed baking sheet.

With knife or scissors, make cuts nearly to the center of ring 1 1/2 to 2-inches apart. Turn each slice on it's side, resting on the adjoining slice. Cover with sprayed plastic wrap and let rise 15-20 minutes.

Remove wrap and bake at 375°F 20-25 minutes or until golden brown.
