In a medium saucepan over medium heat, combine the 28 oz of whole tomatoes, minced garlic, and 1 tablespoon of olive oil. Add 1 teaspoon of white wine vinegar, 1 teaspoon of dried oregano, salt, and black pepper. Let this simmer for 10-15 minutes, stirring occasionally, until the sauce thickens and flavors meld beautifully.

Preheat your oven to 375°F (190°C). While the oven heats, take 3 ten-inch flour tortillas and cut them into mini circles using a cookie cutter or a large glass as a guide. Lightly brush both sides of each tortilla with the remaining olive oil.

Place the tortilla circles on a baking sheet lined with parchment paper. Spread 1 to 2 tablespoons of the tomato sauce evenly on each tortilla circle. Then, sprinkle shredded mozzarella cheese over the sauce.

Slice the black olives into spider bodies and legs or cut the cheddar cheese into ghost shapes using cookie cutters. Arrange these toppings on the sparkling cheese.

Bake the decorated mini pizzas in the preheated oven for 8-12 minutes, looking for a bubbly, golden cheese topping and a perfectly crisp tortilla base.

Remove the mini Halloween pizzas from the oven and allow them to cool slightly for about 5 minutes. Serve them warm on a festive platter.
