4 boneless skinless chicken breast halves (4 ounces each)
4 slices Swiss cheese
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° until a thermometer inserted in the chicken reads 170°, about 15 minutes. Top with slice of Swiss cheese; bake until cheese is melted and pastry is golden brown, about 5 minutes longer.
