Preheat your oven to 350° F
Oil a roasting pan that is large enough to hold the fish.
Transfer the fish from the lime mixture to the roasting pan.
If the tail sticks out of the pan, wrap it in foil to prevent from burning.
Cover the fish with the hot tomato sauce.
Bake in the center of the oven until the flesh flakes at the thickest part of the fish. About 50-55 minutes.
Transfer the fish to a large serving platter, remember to support the whole fish while transferring, it is tender.
Ladle the sauce over the fish.
Garnish with the remaining olives, capers, and jalapenos.
