Bring a medium pot of water to the boil then add the brussels sprouts and cook for 2 - 3 minutes.

In a large pan on a medium to high heat cook the bacon until crispy. Remove from the pan leaving all the juices in the pan add the onions and cook until nice and soft, if the pan seems a little dry add a dash of olive oil.

Remove the brussels sprouts using a slotted spoon or a small sieve and add them to the onions and sauté until they have some colour on them or are cooked, add a tiny bit of salt if needed.

Bring the water that the brussels sprouts back to the boil, add some salt and top up with a bit of water if needed. Cook the pasta as per instructions but 1 - 2 minutes before it is finished remove from the pot with the sieve or slotted spoon and add to the brussels sprouts. Break up the bacon into small piece and sprinkle over the pasta (keep a bit aside to serve with) and give it a good mix then add the gorgonzola and 2 - 3 tablespoons of the pasta water and give another good mix. Mix through some walnuts and check the seasoning and add some black pepper.

Once the pasta is cooked serve with a little sprinkle of bacon and walnuts over the top.
