1-First, preheat the oven to 475°F (246°C) and arrange the cut bagel halves on a baking sheet with four cut sides facing up. Spread 1/4 cup marinara evenly on two bagel halves, then top each with 2 tablespoons mozzarella and 6 slices pepperoni. Drizzle the olive oil over the other two bagel halves and sprinkle each with 1 tablespoon parmesan; add a slice of prosciutto to each.

2-Baking and Finishing Touches: Bake for 8 to 10 minutes until the cheese melts, pepperoni crisps, and prosciutto turns slightly crispy. After baking, sprinkle the pepperoni pizzas with extra parmesan, add dollops of fig preserves to the prosciutto pizzas, top with arugula and goat cheese, and finish with a drizzle of balsamic glaze before serving.

3-Preheat your oven to 375°F (190°C) and prepare your workspace by gathering all ingredients. Slice the bagels in half horizontally and place them on a baking sheet lined with parchment paper. Spread a generous layer of tomato sauce evenly over each bagel half, then sprinkle shredded mozzarella cheese and add toppings like pepperoni or vegetables. Season with oregano and bake for 10-12 minutes until the cheese bubbles. For dietary adaptations, use vegan cheese or gluten-free bagels and adjust as needed for the best results.
