Remove CAULIPOWER Cheese Pizza from freezer and bake until almost finished.
While the pizza is cooking, use a knife or ghost shaped cookie cutter to make ghosts out of the slices of mozzarella.
Remove pizza from oven and top with ghost mozzarella slices. Cut shapes out of the olives to create the eyes and mouth for the ghosts and place them on top of the mozzarella.
Add the topped pizza back into the oven until the mozzarella ghosts are cooked. Slice and enjoy!
