01 - Toast all 6 slices of sandwich bread until golden brown and lightly crisp on the surface.
02 - Spread mayonnaise evenly over one side of each toasted bread slice using a butter knife.
03 - Place 2 toasted slices mayo-side up on your work surface. Layer each with half of the turkey or chicken, 1 slice of ham, 2 strips of bacon, sliced tomato, and lettuce leaves. Season lightly with salt and pepper.
04 - Top each sandwich with a second toasted bread slice, mayo-side up, pressing gently to settle the layers.
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.
06 - Place the final toasted bread slice on top of each sandwich, mayo-side down. Insert 2 toothpicks into each sandwich to hold the layers together.
07 - Using a sharp knife, cut each sandwich diagonally into 4 triangular wedges. Serve immediately with chips or a side salad.
