Pound 6 boneless chicken breast halves until 1/4 inch thick. Sprinkle with salt and pepper. Top each piece of chicken with 1 slice of ham and 1 slice Muenster cheese. Fold chicken over ham and cheese. Wrap each bundle in two strips of bacon. Place bundles side by side in a shallow baking pan. Bake in a preheated oven at 350 degrees for 40 to 45 minutes or until chicken is cooked and bacon is browned. Garnish with parsley.
