Steps
- Preheat the oven to 230°C (210°C fan-forced). In a large non-stick frying pan, heat 1 tablespoon of olive oil over medium heat. Add the sliced onions, season with salt and pepper, and cook, stirring occasionally, for about 15 minutes or until caramelised.
- While the onions are cooking, combine the oregano, crushed garlic, and the remaining olive oil in a small bowl, mixing well. Place the pizza bases on two large baking trays and spread the oregano mixture evenly over each base.
- Top the pizza bases with the caramelised onion mixture, grated mozzarella, halved grape tomatoes, pieces of blue mackerel, kalamata olives, and sliced red chillies. Bake in the oven for about 20 minutes, or until golden and crisp. Remove from the oven, sprinkle with baby rocket leaves, and serve with lemon wedges.
