Italian sausages are usually seasoned with fennel and really add something special to this simple recipe.
Cook the pasta in salted boiling water until al dente.
In a frying pan, heat the olive oil and shallow fry the onion and sausage until golden.
Add the mushrooms, chilli and the pine kernels, season with salt and pepper and cook for approximately three minutes.
Drain the pasta, add to the sauce and mix well.
Serve immediately with some freshly grated pecorino on top.
