Bring a pot of salted water to a boil and cook the dry pasta according to package directions until al dente.
While the pasta cooks, heat the olive oil in a large skillet over medium heat and add the prosciutto, cooking until it becomes crisp.
Remove the crispy prosciutto from the skillet and set it aside on a paper towel, then add the diced chicken breast to the same pan.
Season the chicken with sea salt and black pepper, sautéing until the pieces are golden brown and cooked through.
Add the minced garlic to the skillet and cook for one minute until fragrant, then reduce the heat to low.
In a small bowl, whisk together the Greek yogurt and parmesan cheese with two tablespoons of the hot pasta water to create a smooth sauce.
Toss the cooked pasta into the skillet with the chicken and garlic, then pour the yogurt mixture over the top.
Stir everything together until the noodles are thoroughly coated in the velvety sauce, then top with the crispy prosciutto and fresh parsley.
