"My family loves Italian food," writes Seamus Ray of Annapolis, Maryland. "One of my best creations is this veal dish with eggplant; I serve it for special occasions."
Melt 2 tablespoons butter in heavy medium skillet over medium-high heat. Add mushrooms and tomatoes; sauté 5 minutes. Add onions; sauté 1 minute. Add wine and simmer until liquid is absorbed, about 6 minutes. Stir in 2 tablespoons butter. Season with salt and pepper.
Preheat oven to 400°F. Cut four 1/2-inch-thick lengthwise slices from center of eggplant. Mix oil and 2 teaspoons rosemary; brush over both sides of eggplant slices. Place slices on baking sheet. Sprinkle with salt and pepper. Bake until tender, about 5 minutes per side. Top each eggplant slice with prosciutto slice. Set aside. Maintain oven temperature.
