1Preheat your oven to 200°C (392°F).
Lightly grease a baking dish with the olive oil.
Place the fish fillets in the baking dish and sprinkle with salt.
Evenly spread the shredded cheese over the fish fillets.
Bake in the preheated oven for 20-25 minutes, or until the fish is cooked through and the cheese is golden and bubbly.
Remove from the oven and let it rest for a few minutes before serving.
