1. Preheat oven to 450°F. 2. Cut the bagels in half down the middle and core out the center; lightly toast. 3. Spread a layer of pizza sauce in each bagel and sprinkle with salt, pepper, garlic powder, and Italian seasoning; add the mozzarella cheese and pepperoni. 4. Bake for ~10 minutes (until bagels are hot and crispy) and then broil for 2-3 minutes to get the cheese golden brown and melty. 5. Enjoy with hot pepper flakes and parmesan!
