Preheat oven to 400° F.
Unroll pizza dough and place on greased baking sheet.
Layer pesto, cheeses, sun-dried tomatoes and chicken breast pieces in middle of dough. Lift one edge of dough and stretch over the filling to form a half-moon. Seal edges by pressing with tines of fork or pizza wheel, and make a fluted edge around the seal.
Prick top with fork to allow steam to escape. Brush with olive oil. Bake in preheated oven 8 to 10 minutes, or until golden brown. Let stand 5 minutes before serving. Garnish with parsley.
