Preheat oven to 375.

If using slim buns, separate the halves.

Take your pizza bases (cracker, bun or pita) and cover with pizza sauce.

Take string cheese and open and pull into strings.

Take 4 strings and lay across the base like you would cut a pizza.

Cut more strings into smaller pieces to go across each "slice" of the pizza.

To make a spider, cut the ends off of 2 olives one slightly large than the other.

These 2 will be the head and body.

Cut 2 slices off of the already cut olive and cut those slices in half to make legs for the spider.

Place on spider on each pizza.

Place on cookie sheet and bake until cheese is melted (about 10 minutes).

You can optionally put eyes on the spider by dipping a toothpick in mustard and touching it to the head.
