Bring a pan of lightly salted water to the boil and add the pasta. Return to the boil and cook for the time on the packet over a fast simmer.
Add the oil and diced chorizo to a saute pan and fry gently for a few minutes to release the flavours and lovely paprika colour.
While the chorizo is cooking cut the bacon rashers into thin strips. Add the bacon strips to the pan and continue to fry over a gentle heat for 5 minutes.
Add the garlic and chilli to the pan and fry for another couple of minutes stirring frequently so the garlic doesn't burn.
Drain the pasta when cooked al dente and add to the pan with the chorizo and bacon in. Stir well to coat the pasta with the pan juices.
Sprinkle over the herbs and give a quick stir to incorporate.
Add the carbonara sauce to the pasta and stir gently for a few minutes until the sauce is warmed through.
Serve in warmed bowls with some grated cheese on top.
