Follow these easy steps to create your Halloween Spider Bagel Bites:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper and spray it lightly with cooking spray.
2. Prepare Bagels: Cut the mini bagels in half horizontally and place them on the prepared baking sheet.
3. Add Sauce: Spoon a generous amount of pizza sauce onto each bagel half, spreading it evenly.
4. Sprinkle Cheese: Top each bagel with shredded mozzarella cheese, ensuring it covers the sauce completely.
5. Bake: Place the baking sheet in the oven and bake for about 10-15 minutes, or until the cheese is melted and bubbly.
6. Make Spider Legs: While the bagels bake, create spider legs by cutting the pretzel sticks in half. You should end up with 16 short pretzel pieces.
7. Decorate: Once the bagels are done baking, remove them from the oven.
8. Assemble Spiders: Press 4 halves of black olives into the cheese on each bagel to form a spider body. Use the pretzel pieces to create spider legs by inserting them into the cheese around the olives.
9. Finish Up: A drizzle of olive oil over the cheese and a sprinkle of Italian seasoning can enhance the flavor.
10. Cool & Serve: Allow the bagel bites to cool for a few minutes before serving to enjoy their warm, cheesy goodness.
