In a large, deep skillet or wide, shallow pot heat the olive oil over medium heat and cook the onion and pepper until soft, about 7 minutes. Add the eggplant and cook another 5-6 minutes, stirring occasionally. Add the tomatoes. Raise heat and bring to a boil. Cover and reduce to a simmer. Cook for about 7-8 minutes, until the sauce thickens a bit and the juices have cooked off. Pour in the wine. Raise the heat again, and bring to a boil. Reduce heat and simmer for 5 minutes.

Season the fish with salt and pepper. Place the fish strips in the pot, gently covering them with some of the vegetable mixture. Cook uncovered for about 12 minutes, or until the fish is fork-tender and the sauce thick. Remove, cool for a few minutes and serve.
