Cook the bacon in a pan until it is nicely crisp, then place it on paper towels to drain the excess fat.
Toast the twelve slices of white bread until golden and slightly crunchy.
Arrange the toasted bread on a flat surface in four groups of three slices each and spread just under one teaspoon of mayonnaise on every slice.
On the first slice of each group, layer one slice of cheddar cheese, followed by a quarter of the turkey, and a few slices of tomato.
Place the second slice of bread on top of the tomato with the mayonnaise side facing down, then spread mayonnaise on the top side of this middle slice.
Add a layer of bacon strips, some lettuce, and then the ham on top of the middle bread.
Finish each sandwich by topping with the third slice of bread, mayo side down.
If you like, secure each sandwich with toothpicks and slice them into halves or quarters.
Serve immediately for a fresh, classic club sandwich experience.
