Let the dough sit at room temperature for 20 minutes before handling so it wil soften. Form the dough into a 10-inch flat, circular shape. Spread the pesto evenly onto the dough. Place the mozzarella cheese, tomoatoes, and artichoke hearts evenly on the dough. Bake the pizza in the oven for 20-25 minutes or until it is cooked all the way through. Remove it from the oven and let it cool for 10 minutes.
