- Heat oven to 200°C/fan 180°C. Line a baking tray with foil. Rub the salmon fillets with a drizzle of olive oil and season well with sea salt and freshly-ground black pepper. Roast in the foil-lined baking tray for 10 to 15 minutes, depending on the thickness of your fillets, until just opaque and easily flaked with a fork.
- Meanwhile, make the mango and avocado salsa: combine the ingredients in a small bowl; set aside.
- To serve, arrange the salmon fillets on a plate and top with the mango and avocado salsa.
