Preparation
Preheat oven to 400˚F.
In a large skillet over medium-high heat, melt the butter with the EVOO and cook the celery and carrots until tender, about 3-4 minutes. Add the chicken and hot sauce to the pan and toss everything together with some salt and ground black pepper. Set aside and let cool.
When the filling is cool, roll out the pizza dough into a rectangle on a floured surface. Spread the cooled filling evenly out onto the entire dough, making sure not to get too close the any of the edges. Top with cheeses and scallions.
