Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
In a large bowl, combine the shredded chicken, buffalo sauce, cream cheese, mozzarella, blue cheese, garlic powder, onion powder, black pepper, and half of the green onions. Mix until well combined.
Roll the pizza dough into a large rectangle.
Spread the buffalo chicken mixture evenly over the dough, leaving about a ½-inch border around the edges.
Roll the dough tightly into a log, starting from one long side.
Slice the log into 1½-inch rolls and arrange them cut-side up on the prepared baking sheet.
Brush the tops with melted butter and sprinkle with parsley.
Bake for 18 to 22 minutes, or until the rolls are golden brown and the cheese is bubbly.
Sprinkle with the remaining green onions before serving.
