Set a large pot of salted water to boil and cook pasta according to the directions on the package. (I usually add 1 tablespoon of water to the pot)
Heat a large skillet over medium heat and add in the olive oil, prosciutto, and onions. Cook until the onions are softened and the prosciutto is starting to brown.
Sprinkle the shrimp with a just pinch of salt and pepper. Use sparingly because the sauce and pasta are already seasoned.
Add the shrimp and garlic to the pan and cook for about 5 more minutes or until the shrimp are pink on both sides.
Mix both sauces together and add to the pan. Stir together to coat the shrimp.
Drain your pasta and add it to the sauce and toss to coat all of the pasta.
Serve with a sprinkle of fresh parsley and parmesan cheese if desireds.
