Place the cod in a 9x13 inch baking dish and spread the tomatoes around it, then drizzle the olive oil over both the cod and the tomatoes.
Sprinkle the sea salt, sliced garlic, and sage over the cod and tomatoes and rub it into the cod, then top the cod with the sliced lemons.
Bake for 45 minutes, until the cod flakes apart easily with a fork, then garnish with capers and serve.
Notes
No time to defrost your fish? No problem. You can bake the fish straight from the freezer. Just add a few minutes of cook time and make sure the fish is cooked through before serving.
