Gather your spooky pizza toppings! Spiralize the zucchini into "worms" and set aside.
Cut the top off a red pepper, and make 3 long cuts along the natural seed lines inside the pepper. Cut all pieces apart, and round the edges a bit to make it look like a tongue.
You need two black olives for each spider. Cut one olive in half, that's the body. Then cut the second black olive in half and slice, the slices are the spider legs.
Time to assemble the frozen pizza! Use the two leftover red pepper pieces for lips, put a round slice of olive on top of the mozzarella balls to make eyes, and add your worms, tongues, and spiders!
Bake the pizza according to package directions and serve hot! Doesn't it look so spooky?!!!
