Cook in a preheated 350F oven for about 20 minutes.
While the fish is cooking, mix about 2 tbls of softened butter with 2 tbls. of tomato paste. Remove the fish from the oven after 20 minutes and brush the Tomato Butter all over the fish.
Return the fish to the oven and cook for about 8 minutes more for the butter to caramelize and help create a buttery sauce for the fish. Remove and allow to cool for about 5 minutes. Serve the fish with the sauce from the pan. It's healthy, fast, fresh and looks a lot more complicated than it is; as they applaud, just smile and nod.
