Preheat the oven to 500°F. Peel string cheese into thin strips and cut olives for spiders.
Stretch out your dough and prick it all over with a fork.
Spread the sauce on the dough, leaving a 1/2-inch border.
Bake the sauced dough until the crust is just golden, 3 to 5 mins.
Remove the pizza from the oven. Make a web with the string cheese strips.
Make spiders using the halved and sliced black olives.
Return the pizza to the oven. Bake until the cheese melts.
