In a large mixing bowl or stand mixer, combine self rising flour and Greek yogurt until a thick dough forms. Dough will be shaggy and thick, but should mostly stick together when pressed into a ball. Roll out dough into a 10"x14" rectangle on a lightly floured surface. Cut the rectangle of dough in half to form two rectangles (to fit in the air fryer).
Spread about 2 tablespoons pizza sauce on each rectangle, leaving a 2-inch border around the edges. Sprinkle 1/2 cup cheese over the sauce on each, then top with pepperoni.
Roll the rectangles of dough up into logs, like you would with cinnamon rolls. Pinch the edges together and tuck and pinch the ends under. Brush the tops of the stromboli with the beaten egg. Sprinkle with Italian seasoning, garlic, and additional cheese. Use a sharp knife to gently cut diagonal slit, every 2 inches, on top of each stromboli.
Preheat air fryer. Spray air fryer basket with oil. Place both stromboli in the air fryer basket, if they will fit without touching each other. Air fry at 340°F for about 10 minutes, until golden brown and cooked through. Let rest for a few minutes, the cut into slices and serve with extra pizza sauce for dipping.
Notes
Any pizza dough will work for this recipe.
Oven Instructions: Preheat oven to 400°F. Spray baking sheet with oil spray. Follow instructions above, but keep stromboli as one big roll and place on baking sheet. Bake for 22-25 minutes, until golden brown and cooked through.
