Halve an avocado and remove the peel.
Slice the avocado thinly lengthwise and flatten it carefully with your fingers.
Use the heart cookie cutter to make the avocado weave hearts and mozzarella hearts (it may help to lift the avocado hearts with a knife).
Cut pieces of tomato along the skin and use the cutter to trim the hearts into the soft side of the tomato.
Slice your bread and top with cream cheese.
Arrange the tomato, mozzarella and avocado hearts on top of the bread.
Drizzle with balsamic glaze, sea salt and fresh basil and serve.
