Preheat the broiler. Pat the frankfurters dry. In a skillet cook the bacon for 3 minutes or until still pliable and not crisp. Transfer to paper towels to drain. Cut a 1 cm slit lengthwise from end to end of each frankfurter. Stuff each frankfurter with the cheese. Wrap the entire length of each frankfurter with 2 slices of the bacon and secure with toothpicks. Place the prepared frankfurters on a rack over a baking pan or on a broiler pan. Broil the frankfurters until the bacon is crispy, about 2 to 3 minutes. Serve frankfurters in rolls.
