Preheat your oven to 400°F (200°C) and place a rack in the middle. Brush the inside of a baking dish with olive oil so it’s lightly coated and big enough to fit the salmon pieces.

Toss together the halved tomatoes, chopped olives, and sliced red onion in a bowl. Pour in the lemon juice, dried oregano, olive oil, salt, and pepper, then mix gently until it’s evenly mixed.

Dry the salmon fillets using paper towels and place them in the oiled baking dish, skin side down. Leave a little space between each one and sprinkle the tops lightly with salt and pepper.
04 -
Spoon the tomato and olive mixture around the salmon fillets. Make sure you include some of the dressing from the bottom of the bowl. Add a drizzle of olive oil over the salmon.

Put the dish in the oven and cook for 15-20 minutes. The salmon is ready when it easily flakes apart with a fork and measures 145°F (63°C) in the center.

Take the dish out of the oven and let it sit for a few minutes. Scatter the fresh basil leaves on top before serving. You can add some lemon wedges on the side for an extra zing.
