SAUCE: Heat oil in saucepan over medium heat. Gently brown 3 whole
garlic cloves and discard. Add oregano, minced garlic and onion and
cook until translucent. Add tomatoes, olives, capers, bay leaves,
thyme, marjoram, salt, pepper and jalepeño. Simmer 2 hours, stirring
occasionally, until sauce is thick. Remove from heat and set aside.
FISH: While sauce simmers, place fish in a single layer in a large
baking dish. Chop marinade ingredients in a food processor and pour
over fish. Cover and refrigerate 1 hour. Preheat oven to 425 degrees.
Remove fish from marinade and place in a single layer in a clean baking
dish. Bake until fish is just done, about 12-15 minutes. Avoid
overcooking.
Re-heat sauce, if necessary and place a thin layer on a serving platter. Arrange fish on top and cover with remaining sauce.
