Preheat oven to 400°.  On lightly floured surface, unroll pizza crust and roll or stretch to a 12 x 12-inch square.  Spread Pizza Sauce evenly over crust, leaving a 1-1/2 inch border.

Arrange chicken evenly over Sauce then sprinkle with cheeses. Gently roll crust to form a log. Fold in ends and pinch to seal. Arrange on cookie sheet, seam side down. Gently press in sides to form 12 x 4-inch loaf.

Bake 35 minutes or until dough is cooked and golden. Let stand 10 minutes.  Cut stromboli into slices and serve with additional heated Sauce for dipping.
