Preheat oven to 375 degrees.
Grease a pizza pan.
Open one pizza crust and press it into a circle on the greased pan.
Top with pesto, chicken, and both cheeses.
Press the other pizza crust into a circle and place on top.
Using a pizza cutter, slice into 16 pieces.
Pick up the outside edge of each piece and twist it 360 degrees.
Bake for about 30 minutes, until top is evenly browned and inside is cooked through.
If desired, brush with melted butter and top with parmesan cheese and italian seasoning.
