Preparing Mediterranean Fish with Tomato and Olive Tapenade is simple. Follow these easy steps:

1. Preheat your oven to 400°F (200°C).
2. Prepare the Tapenade: In a mixing bowl, combine the chopped olives, capers, minced garlic, and 2 tablespoons of olive oil. Stir well, and set aside.
3. Prepare the Tomatoes: On a baking sheet, spread out the halved cherry tomatoes. Drizzle with olive oil and season with salt and pepper to taste.
4. Add the Fish: Place the fish fillets on top of the tomatoes. Drizzle a little olive oil over the fillets and season with salt and pepper.
5. Bake: Put the baking sheet in the oven and bake for 20-25 minutes or until the fish flakes easily with a fork.
6. Finish the Tapenade: Stir the prepared olive tapenade before serving to ensure all the flavors meld together.
