Preheat the oven to 150c (fan assisted).
Season the beef and pork with salt and pepper then take a large sauce pan, spray with 1kal and on a medium/high heat add the beef shin to the pan and brown on all sides. Remove from the pan, pop to one side and then do the same with the pork shoulder. Remove from the pan.
Spray the same pan with 1kal again and add the carrot, onion and celery. Fry on a medium heat until everything begins to soften (6-8 minutes). Add the garlic and anchovies and fry for another minute.
Add the nduja to the pan, fry for a minute or two until the oils start releasing and it starts to breakup and then add the tomato puree. Stir, fry for a minute and then add the red wine to the pan. Reduce the wine for a few minutes and then add the beef stock, tomatoes, bay, thyme, rosemary and oregano. Add the beef and pork back to the pan (chop into a few large chunks if you are struggling to get the meat to fit), make sure the sauce covers the meat and season well. Bring to the boil and then take off the heat, add the lid and then pop in the oven for 3-3.5 hours.
Once the cooking time is up the meat should be falling apart. You can either shred the meat in the sauce or take it out the pan and shred it on a plate. Either way, once shredded, put the pan back on the heat (with the meat and sauce) and reduce the sauce if it is still too thin until it thickens up. Adding the meat will help with this anyway.
Finally add the parmesan, stir and then season with salt and pepper to taste.
Serve with pasta of your choice.
Enjoy!
