On an ungreased baking sheet, separate dough into four rectangles; seal perforations. Spread 1 tablespoon cream cheese lengthwise down the center of each rectangle. Place ham widthwise over dough. Arrange chicken in center of each rectangle. Wrap ham around chicken. At each long end, pinch dough together around chicken, forming points.
Bake at 375° for 15 minutes. Top with slice of Swiss cheese; bake 5 minutes longer or until cheese is melted and pastry is golden brown.
