Sprinkle the fish with pepper to taste. Wrap a slice of prosciutto around each fish fillet. If the fillets are large or the prosciutto slices are small, you may need to overlap a second piece to fully cover. (At this point, you may cover and refrigerate until ready to eat.)
Coat a large skillet (non-stick or seasoned cast iron work well) lightly in olive oil and heat over medium-high heat.
When hot, place the prosciutto-wrapped fish in the skillet and cook for 2–3 minutes on each side, until the prosciutto is golden and crispy and the fish is just barely cooked through. The fish will continue to cook a bit after it has been removed from the heat.
Serve with your favorite green vegetable, a baked potato and/or a side salad…or whatever sounds good to you!
