Brush baguette slices with olive oil. Place, oiled side down, in the skillet and cook just until toasted, about 3 minutes. You can also do this step by placing the baguette slices on a baking sheet and placing them under the broiler for a couple of minutes.
Transfer to a serving plate. Place sliced prosciutto and basil leaves on top. Drizzle with more extra virgin olive oil and a few grinds of fresh black pepper. Serve.
