Season fish fillets with spice. Heat oil in a saute pan, add fillets and sear until golden brown. Turn carefully and sear second side until golden brown. Add olives, tomatoes, eggplant, onion, garlic, and herbs. Stir vegetables around taking care not to break fish, 3 minutes. Add 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 adjust seasonings to taste with salt and pepper. Serve fish with generous spoonfuls of sauce and vegetables.
