Step 1

Preheat oven to 240C/220C fan forced. Spread the pizza bases with tomato paste.

Step 2

Sprinkle with half the pizza cheese. Top with the ricotta and chilli flakes, if using. Arrange the zucchini, tomato, stuffed olives and basil on top. Sprinkle with the remaining pizza cheese then spray with olive oil. Season. Bake directly on the oven racks for 10 minutes or until cheese is dark golden and base is crisp. Drizzle over oil and balsamic glaze, if using.
