Boil the fettucine in water according to the pack instructions - this usually takes around 10 minutes.

Meanwhile, add some butter to a large skillet, and slowly warm it through over a low-medium heat. Pour in some heavy cream and stir well.  Next, add some shredded Parmesan, a little at a time, stirring constantly to incorporate it into the sauce.

Season with salt and pepper to taste, then add the chopped (cooked) sausages, stir to mix, and cook until the sausages have warmed through. 

Mix the cooked noodles into the sauce, turn to coat, then transfer to two serving plates or bowls. Serve with a garnish of chopped fresh parsley.
