Creating Buffalo Chicken Pizza is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 450°F (230°C).
2. Prepare Chicken: In a medium bowl, mix the shredded chicken with Buffalo sauce until well-coated.
3. Prepare Pizza Crust: If using a pre-made crust, place it on a pizza stone or baking sheet. Brush the edges with olive oil for a golden finish (optional).
4. Spread Sauce: Drizzle ranch dressing evenly over the pizza dough, leaving a small border at the edges.
5. Add Chicken: Sprinkle the Buffalo chicken mixture evenly over the ranch dressing.
6. Add Cheese: Top the chicken with shredded mozzarella cheese, ensuring even coverage.
7. Bake: Place the pizza in the preheated oven and bake for 20-25 minutes, or until the crust is golden and the cheese is bubbly.
8. Garnish: Remove the pizza from the oven and let it cool for a few minutes. Sprinkle with chopped green onions.
9. Slice and Serve: Cut the pizza into slices and serve while hot.
