2. In a large mixing bowl, combine the shredded chicken, buffalo sauce, ranch dressing, and half of the chopped green onions. Stir until well combined.
3. Roll out the refrigerated pizza dough on a floured surface to about 1/4 inch thickness and cut into 8 squares.
4. Take one square of dough, place a spoonful of the chicken mixture in the center, and sprinkle with mozzarella cheese. Fold the dough over the filling to create a pocket and pinch the edges to seal.
5. Place the sealed pizza bombs on a greased baking sheet, brush the tops with the beaten egg, and bake for 15-20 minutes until golden brown and puffed.
6. Let cool slightly before serving, and garnish with remaining chopped green onions and extra ranch dressing.
