Pour the stock into a pan and bring to a simmer. Add the squash and chicken, cover and bubble gently for 15 mins, or until the chicken and squash are cooked. If the chicken cooks first, remove from the pan, set aside and keep boiling the squash until tender. Scoop the squash out with a slotted spoon, leaving just the stock in the pan.

Bring the stock back to the boil and add the pasta; the liquid should just cover the pasta. Cook, stirring regularly, until the pasta is just tender and most of the stock has been absorbed (top up with water if necessary). Shred the chicken.

Return the squash to the pan and add the cream cheese, pecans, parsley and parmesan. Simmer for another min or two, then add the chicken. Season and serve with extra parmesan, if you like.
