Prepare Fettuccine Alfredo, reducing the butter to 1 tablespoon. Melt the butter in a skillet and cook 4 ounces prosciutto, chopped, until crisp. Add the cream to the skillet and bring to a simmer. Stir in 1 cup fresh or frozen peas and cook 2 minutes. Stir in the pasta, Parmesan, salt, and pepper.
