Preheat oven to 450°F. Spread the pizza dough onto a pizza stone or baking sheet. Evenly distribute 1 1/2 - 2 cups tomato sauce out to the edges of the pizza dough. Drain, pat dry and quarter the artichoke hearts and distribute them around the pizza. Pinch off small pieces of the goat cheese and distribute them around the pizza. Finish by topping with kalamata olives. (Optional: Sprinkle liberally with olive oil) Bake for 20 minutes, or until edges are nicely browned and cheese is bubbling.
