Toast tower with mozzarella

Preparation

Using the pastry ring, cut circles out of the toast bread and place them in the toaster.
On a plate, layer a toast round, a slice of mozzarella, a slice of tomato, another toast round, and another slice of mozzarella. Then roll up a slice of ham with some spring onion rings and place the roll on top of the mozzarella. Place the final toast round on top.
Finish with a spoonful of mayonnaise, watercress, and spring onion.
Insert a wooden skewer through all the toast layers.
