Creating Mini Halloween Spider Pizzas is straightforward. Follow these steps:

1. Preheat the Oven: Set your oven to 400°F (200°C) to prepare for baking.
2. Prepare the Dough: Roll out the pre-made pizza dough on a floured surface to about ¼ inch thick. Use a round cutter to cut mini pizzas, about 4 inches in diameter. Re-roll any scraps of dough as needed.
3. Place on Baking Sheet: Arrange the cut-out mini pizzas on a baking sheet lined with parchment paper.
4. Add Pizza Sauce: Spoon a small amount of pizza sauce onto each mini pizza, spreading it evenly with the back of the spoon.
5. Sprinkle Cheese: Generously sprinkle shredded mozzarella cheese over the sauce on each mini pizza.
6. Create Spiders: For each mini pizza, place pieces of pepperoni cut into small circles for the spider body. Use olive slices to make the legs. Arrange four pieces on each side of the pepperoni body.
7. Bake: Place the baking sheet in the preheated oven and bake for 12-15 minutes or until the cheese is melted and bubbly, and the edges are golden brown.
8. Cool and Serve: Once baked, remove the mini pizzas from the oven and allow them to cool slightly. Optionally, garnish with fresh basil leaves before serving.
