Cook the waffle fries according to the package instructions.
Preheat the oven to broil. Put the pizza sauce in a microwave-safe bowl and microwave until hot.
Put the hot fries on a large heatproof plate or platter. Top with the pizza sauce, half of the pepperoni, the cheese and the remaining pepperoni. Broil until the cheese is melted and bubbly, about 3 minutes. Top with the banana peppers.
