This is adapted from my local newspaper. Any mild white fish will work here. This dish is easy to prepare. Kalamata olives are the black Greek olives, but you can substitute nearly any olive you prefer.
Heat oil in a Dutch oven or deep skillet over medium high heat. Add garlic and onion and saute, stirring until the onions begin to soften, about 3 minutes. Add oregano and thyme, stir. Add tomatoes, olive, capers and about half the parsley. Simmer until tomatoes cook down to a chunky sauce.
Sprinkle fish with salt on both sides. Push some of the sauce to one side of the pan and spread the rest thinly over the bottom of the pan. Place the fish on top of the sauce in the bottom of the pan and cover with the sauce that you previously pushed aside. Cover the pan and simmer over medium heat until the fish is opaque and flakes easily, about 10 minutes.
Sprinkle the remaining parsley over the fish and serve.
