Rub the 2 pounds boneless chicken breasts with Kosher salt and ground black pepper, and 1 tsp of the 1 tablespoon dried oregano on both sides.
Heat 1 tbsp of the 2 tablespoons olive oil in a large skillet over medium heat.
Add chicken and cook, until cooked through and golden-brown on both sides, about 10-12 minutes. Set aside on a plate. You might have to cook the chicken in batches to avoid overcrowding the pan, so divide the oil if so.
Add the remaining 1 tbsp of oil to the hot skillet, and sauté the 3-4 cloves garlic (minced) and 4 anchovy fillets (chopped) for 1 minute.
Add in the 28 ounces peeled tomatoes with juices and the rest of the oregano. Use the back of a wooden spoon to crush the tomatoes into small pieces.
Stir in the 1/4 cup capers, and 1 cup pitted Kalamata olives; Simmer over low heat, partially covered, for 8-10 minutes until the sauce thickens.
Taste the sauce and season with salt and pepper, if needed.
Return the chicken to the pan and spoon over the sauce. Allow it to cook for a bit more into the sauce, until hot.
Garnish with Fresh parsley (chopped) and enjoy. Serve with warm Crusty bread.

Notes
Chicken: If you want to use seafood, any fish would work. A great substitute would be cod or salmon.
You may make your own homemade peeled tomatoes instead of using canned
Anchovies can be optional but will add a great taste.
