Combine the cranberry sauce and mayonnaise in a small bowl. Stir to fully blend. Toast both sides of the bread in a long toaster or under the broiler in your oven. Stack the sandwich, beginning with a slice of toast topped with a thin layer of cranberry mayonnaise. Add turkey, cheese, tomato, lettuce. Add another slice of toast topped with a thin layer of cranberry mayonnaise. Add bacon, more turkey (if desired), cheese, tomato, and lettuce. Add salt and pepper to taste. Spread a thin layer of cranberry mayonnaise on the last slice of toast and top the sandwich. Press the sandwich down gently and poke a short skewer or long toothpick through each half of the sandwich. Cut the sandwich in half with a serrated knife, using a sawing motion to prevent displacing the ingredients. Serve immediately.
