Top one slice of bread with stuffing, a thin layer of gravy, ¼ of the turkey and three slices of bacon. Add another thin layer of gravy. Spread one fourth of apple butter/cranberry mixture on the other slice of bread. Add salt and pepper to taste. Assemble the sandwich. Repeat for the remaining three sandwiches.
