Spread 1 tablespoon of pizza sauce at the bottom of a flour tortilla, leaving ¼ inch at the edge.
Lay 10 slices of pepperoni on top of the sauce.
Place one string cheese on top of the pepperoni.
Carefully and tightly roll up the tortilla and lay it seam-side down.
Repeat for the remaining pizza rolls.
Remove the air fryer basket and lightly spray it with nonstick cooking spray.
Preheat the air fryer to 375°F (190°C) for 3-4 minutes.
Use a pastry brush to lightly coat the tops of the pizza rolls with olive oil.
Lay 3-4 pizza rolls in a single layer in the air fryer basket, leaving a little space between them.
Cook for 9-10 minutes, or until golden brown and crispy.
Serve warm with extra pizza sauce or ranch dressing for dipping.
