Slice the sourdough and add on the tomato paste (or sauce), I did a little bit of both for this one. Then I added garlic powder and black pepper. Next I layered on the mozzarella cheese, yellow and orange peppers, onions, green onions, olives, and feta cheese. Lastly sprinkled EVOO on top, and popped it in the oven at 350 degrees and baked until cheese is melted.
