Sprinkle the tomatoes with salt and leave to drain for 30 minutes
Toast the bread until lightly golden. Lay four slices of toast on the surface and spread with mayonnaise.
Rip the lettuce into bite size pieces and place on top of the mayonnaise. Top with the tomato slices, then a slice of ham. Place another slice on toast on top and repeat to make a double-decker sandwich.
Cut each double-decker into three strips and secure with cocktail sticks before serving.
