Buffalo Style Chicken Pizza

3 skinless, boneless chicken breast halves - cooked and cubed
2 T. butter, melted
1 tsp crushed oregano
1 bottle (2 oz) tobasco sauce
1 cup blue cheese salad dressing
1 (16 inch) prepared pizza crust
(or you can make your own, just prebake it for 10 minutes before adding toppings.)
2 cups shredded mozzarella cheese
grated parmesan cheese, to taste

Preheat oven to 425F. In a medium bowl combine chicken, melted butter, oregano, and hot sauce. Mix well. Spread blue cheese dressing over crust, then top with chicken mixture and sprinkle with mozzarella and parmesan cheese. Bake until crust is golden brown and cheese is bubbly, about 5-10 minutes.
Let set a few minutes before slicing, and serve.
