Preheat oven to 400 degrees.

Shape pizza dough into a large circle on a baking sheet. Spread with pesto sauce. Sprinkle with cheese.

Arrange pepperoni slices in an oval for the spider body in the center of the pizza. Arrange 4 slices of bacon on each side of the oval, tucking ends of bacon under pepperoni slices.

Place 2 olive slices at one end of oval for eyes.

Bake for 12-14 minutes, until cheese melts and crust is lightly browned.
