Pre-heat broiler. Place the chicken breasts on a cutting board, cover with some plastic wrap. Using a meat mallet or heavy skillet, pound chicken into 1/2 inch cutlets. Season with seasonings. Heat evoo in large iron skillet or oven-safe pan over med.-high heat. When hot, add the chicken and cook for 3 - 4 minutes, until it has a nice crust, flip and cook on the other side 3 - 4 minutes longer. Remove from pan. In the same pan, add onions, olives, garlic, and pepper flakes. Saute until onions lightly caramalize. Add tomatoes and then add chicken back to the pan. Sprinkle with Parmesan, top with mozzarella. Place pan under broiler until the cheese is melted and bubbling. Keep a watch on it so it won't burn. You may want to scotch oven door open a bit so it won't get too hot.
