This easy dish is not only delicious, but also very fast to prepare. This is how you make it:
Season barramundi with salt for 5 minutes before cooking. Heat a large pan over medium heat. Add 2 tbsp olive oil before adding barramundi skin-side down. Press fillets flat onto pan for about 4 minutes until skin is crisp. Turn and cook for about 1-2 minutes until just cooked through. Remove and place on warm plates, skin-side up.
To make the warm dressing, add remaining olive oil to the pan with olives, preserved lemon, cherry tomatoes and capers. As soon as the cherry tomatoes soften and release their juices, add the basil leaves and toss well.
Place barramundi on individual plates and spoon warm tomato dressing over top. Scatter with pepper and rocket leaves. Squeeze lemon juice over top and serve.
