01 - Toast all 6 bread slices in a toaster until golden brown and lightly crisp.
02 - Spread mayonnaise evenly over one side of each toasted bread slice.
03 - Place 2 toast slices mayo-side up on a clean work surface. Layer each with half of the turkey or chicken breast, a slice of ham if using, 2 strips of bacon, sliced tomato, and lettuce leaves. Season lightly with salt and pepper.
04 - Top each assembled layer with a second toasted bread slice, mayo-side facing up.
05 - Repeat the layering on each sandwich with the remaining turkey or chicken, ham, bacon, tomato slices, and lettuce. Season again with salt and pepper to taste.
06 - Cap each sandwich with the third toasted bread slice, mayo-side facing down. Insert 2 toothpicks into each sandwich to hold the layers together.
07 - Using a sharp knife, cut each sandwich diagonally into quarters to create classic club wedges. Serve immediately with chips or a side salad.
