Preheat oven to 500º F. Drizzle olive oil onto a rimmed baking sheet pan or a pizza pan, enough for a 14-inch pizza. Work pizza dough onto the pan. Drizzle additional olive oil on top of the pizza dough. Using a rubber spatula or the back of a spoon, spread the ricotta cheese over the crust, leaving an edge to the dough for the crust. Then top with shredded chicken, artichoke, mozzarella slices and finally with Parmesan cheese.
