2Pound chicken breasts to a thickness of 1/4 inch. Place one slice Swiss and one slice ham onto each breast, leaving the outer 1/2 inch uncovered. Roll chicken over filling, dip in flour mixture to coat on all sides, and secure with toothpicks.
3Melt butter in a large skillet over medium-high heat. Add chicken and cook, turning occasionally, until browned on all sides, 5 to 8 minutes. Add wine and bouillon. Reduce the heat to low, cover, and simmer until chicken is no longer pink in the center and the juices run clear, about 30 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
