1/4cuppitted kalamata olives, sliced in half, lengthwise
1/4cupcrumbled feta cheese
Preheat the oven to 500 degrees F. (A lesser temperature will work, as well, with just a little longer cooking time.)
Roll dough out to form a large round. Brush with olive oil and sprinkle with garlic salt, to taste. Spread half of the mozzarella evenly over the top, then add the rest of the toppings, ending with the other half of the mozzarella, then the feta cheese.
Bake in the preheated oven for 8 to 12 minutes, or until the crust is baked through and golden brown.
