Good ol' bagel pizzas, for when you need a quick and tasty snack.
On the bottom half of the bagel, spread the tomato sauce, then add the cheese, onion, bell pepper and pepperoni. Top it with the other half of the bagel.
Turn the toaster oven up to 425 F.
Place the full bagel in the preheated toaster oven and toast it until golden brown, about 10 minutes.
