Using a sharp knife, make a wide horizontal slit in each chicken breast. Put the cheese inside, wrap a slice of bacon around the stuffed breast and secure with a toothpick.
Prepare the grill and let the coals burn down to medium gray with a red underglow. Arrange the breasts on the center and cook until browned and cooked through, about 7 minutes on each side.
