Line a cookie sheet with parchment paper.
Pour 4 cups of water into a saucepan and bring to a boil.
While the water comes to a boil, open your pizza crust but do not unroll it. Cut into 8 slices, about 1 inch thick. Cut each slice into quarters (for 32 total pieces). Roll each one individually into a ball. The shape might not be perfect ball, but it will work, trust me.
Once the water is at a rolling boil (boiling in the center, not just around the edges), turn the heat to warm and stir in baking soda.
Working in batches of 4-6 balls, dunk balls into the water for 20 to 30 seconds.
Place balls onto prepared cookie sheet. Brush with egg wash and sprinkle with kosher salt.
Working in batches, place the balls in the air fryer basket (my Cosori holds about 9-11 per batch). The balls might look like they're falling apart but they'll glue together as thy cook.
It is important not to overcrowd your air fryer otherwise the bites won’t cook evenly.
Cook at 350°F for approximately 5 to 7 minutes or until nice and golden. The later batches might take less time since the fryer is already hot.
