In a large non-stick skillet over medium heat, place the fish rolls in the oil, seam side down. Cook for 8 to 10 minutes or until the prosciutto is crispy on all sides. Off the heat, let the fish rest in the pan to continue cooking in the residual heat until the desired doneness is reached. Serve with
Zucchini and Tomato Concassé and, if desired, mashed potatoes and vegetables.
