Let's cook.
Preheat your oven to 400°F (200°C).
Pat the cod fillets dry with paper towels. Season both sides of the cod with salt and pepper.
In a medium bowl, combine the halved cherry tomatoes, halved Kalamata olives, minced garlic, and dried oregano. Drizzle with olive oil and toss gently to combine.
Arrange the seasoned cod fillets in a single layer in a baking dish. Spoon the tomato and olive mixture evenly over and around the cod.
Bake for 12-15 minutes, or until the cod is opaque and flakes easily with a fork. Do not overcook to ensure the fish remains moist.
Serve immediately with your favorite side dishes.
