1. Rinse the fish and place it in a bowl with garlic, lemon juice, salt, and pepper.  Let the fish marinate while you prep everything else. 


2. Heat the oil in a skillet over medium heat. Add the onions, green pepper, tomatoes, coriander, and tomato paste , stirring occasionally. Cook for 8 minutes, until the vegetables are softened. Bring the mixture to a boil and add the fish fillets and the marinade. Lower the heat to medium and cook for 5 to 8 minutes.
3. When the fish is almost done (after approximately 5 minutes), add the coconut milk and bring the mixture to one last boil for about a minute. 

Serve hot over brown rice.

Note: you may substitute other whitefish fillets for the cod.
