Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it for easy cleanup.
Slice the bagels horizontally in half to create 8 rounds, then arrange them cut side up on the prepared baking sheet.
Using a spoon, spread about a tablespoon of tomato sauce onto each bagel half, covering the surface evenly.
Sprinkle a generous layer of shredded cheese over each sauce-topped bagel, creating a bubbly, cheesy base.
If desired, add small bits of your favorite toppings—like slices of pepperoni, chopped basil, or caramelized onions—on top of the cheese for extra flavor and color.
Place the baking sheet into the preheated oven and bake for 8-10 minutes, or until the cheese is bubbling and golden brown around the edges.
Remove the baking sheet from the oven and let the bagels cool for a minute or two until they're safe to handle, and the cheese has set slightly.
Gently transfer the mini pizza bagels to a plate or platter. Serve hot and enjoy their crispy, cheesy goodness with your favorite sides or fresh herbs.
