Toast the bread then lightly butter both sides of each slice. Spread some mayonnaise on one side of each of those slices. Lightly salt the sliced tomato. Layer the turkey, tomato, and cheddar on four of those slices. Place another piece of the toast on top of that mayonnaise side up.
Layer the ham, bacon and lettuce. Top with another slice of bread mayonnaise side down. Secure the sandwich’s layers with frill picks in the center of the four sides of the toast (see picture). Slice into quarters with a sharp or serrated knife.
