01 - Cook turkey bacon according to its label and set aside. Butter one surface of each bread slice.
02 - Build two sandwiches with buttered surfaces outward: cheddar, thin apples, two bacon slices and another cheddar slice.
03 - Cook over medium-low heat, turning carefully, until both sides are golden and cheese melts. Cover briefly if the center needs more warming.
04 - Rest briefly and slice. Keep surplus apple separate rather than making the sandwich too tall to heat evenly.
