Toast the bread until golden but still slightly tender at the center.

Spread mayonnaise over one side of every toast slice.

Top two slices with folded turkey and lettuce, then add a second toast slice mayonnaise-side up.

Add bacon and tomato, season the tomato with salt and pepper and close with the final toast slices mayonnaise-side down.

Secure each sandwich with four toothpicks, cut into four triangles and serve immediately.
