Bring a large pot of salted water to a boil. Prepare the ingredients as stated above (finely slice the shallot, roughly chop the cavolo nero and prepare the stock).
Remove the sausages from their casing and brown in a large frying pan or skillet breaking them up with the side of a wooden spoon.
Once browned, add the shallots to the sausage along with the chilli flakes and fennel seeds and saute for a few minutes until soft.
Once soften, add the white wine and reduce by half (1-2 minutes). Add the cavolo nero and stock and cover with a lid for 7-8 minutes.
At this point, add the pasta to the salted boiling water and cook until al dente (about 8 minutes depending on the brand).
After 7-8 minutes, uncover the pasta sauce and add ⅓ cup of pasta water (80ml) and let it simmer. Once the pasta is ready add the pasta to the sauce with the parmesan, Stir everything together for 1-2 minutes until the pasta is coated in the sauce, serve.
