Season fish fillets with spice and lightly dust with flour. Heat oil in a large saute pan, add fillets and sear until golden brown. Turn carefully and sear second side until golden brown. Remove from the pan and set aside. Add the olives, tomatoes, onion, garlic, and herbs. Stir vegetables around and cook for 3 minutes. Return the fish to the pan, add the stock, bring to a boil, lower heat and simmer to reduce slightly, carefully turning fillets several times to cook evenly. Whisk in butter a few pieces at a time and fold in the eggplant. Adjust seasonings to taste with salt and pepper. Serve fish with generous spoonfuls of sauce and vegetables, and extra-virgin olive oil if desired.
