How to Make It
Place prosciutto in a single layer on a plate lined with paper towels. Cover with another layer of paper towels. Microwave at HIGH until crisp, about 1 1/2 minutes. Let stand 2 minutes; crumble into large pieces.
Bring milk, stock, and flour to a boil in a large skillet over medium-high. Cook, stirring often, until thickened, about 3 minutes. Stir in pepper, rind, salt, and cream cheese. Reduce heat to low; keep warm.
Bring 2 quarts water to a boil in a Dutch oven. Add pasta and carrots; cook 4 minutes. Add peas; cook until pasta is tender, about 3 minutes. Drain pasta mixture; add to sauce in skillet, and toss to coat. Sprinkle with prosciutto, Parmesan, and parsley.
