Spray the bottom of air fryer with non-stick spray and place a piece of parchment paper down. Then, preheat air fryer to 325°F. Flour your workspace well and roll out the pizza dough into an 8″x12″ rectangle.
Brush the surface of the pizza dough lightly with olive oil to prevent the filling from making your pizza rolls soggy. Spread ½ cup of pizza sauce evenly across the surface of the dough. Make sure to leave a 1-inch gap around the edges so you can seal the roll.
Sprinkle lightly with Italian seasoning and garlic powder. Top evenly with chopped spinach and bell peppers.
Sprinkle 1 cup of the mozzarella cheese evenly over the dough.
Starting on the long end of the rectangle, tightly roll the dough like you would with cinnamon rolls. The tighter the better.
Adjust the roll so the seam-side is face down on your countertop and using a sharp knife, cut 10 – 12 individual 1-inch rolls. Carefully tuck the dough around the fillings if some fell out when cutting the rolls and pinch the bottom of each roll (as best as possible) to seal the sauce and cheese inside. Dip the bottom of each roll into cornmeal if desired.
Evenly space out the rolls in your pre-heated air fryer – they should NOT touch. Leave about ½ inch of space between each. Cook in two batches if your air fryer is too small. Top each roll with remaining ½ cup of shredded cheese.
Air fry at 325°F for 10 – 14 minutes, until the cheese is melted and the dough is puffy and cooked through. Check at the 10 minute mark and add time as needed. Remove from the basket and cool down for a few minutes before serving with extra pizza sauce, marinara sauce, or pesto.
