Sear the fillets for 2 to 3 minutes on each side. Remove from the pan and set aside. Add the eggplant and onions to the pan. Season with salt and pepper. Saute for 3 to 4 minutes. Add the tomatoes,
olives,
garlic, green onions, and
herbs. Season with salt and pepper. Saute for 2 minutes. Add the
reduction and bring to a boil.
Simmer for 2 minutes. Return the fillets to the pan. Cook for another 2 minute, basting the fillets with the sauce. Remove from the heat. To serve, mound the potatoes in the center of each plate. Lay each fillet on top of the potatoes. Spoon the sauce around the grouper.
