Using a small amount of flour, dust your Ooni pizza peel. Stretch the pizza dough ball out and lay it out on your pizza peel. With a large spoon or ladle, spread an even layer of pizza sauce over the base of your pizza. Top with mozzarella, ham, spicy pepperoni, and diced pineapple. Finish with a sprinkle of sliced jalapeños, as many as you dare!
