First heat your olive oil in a large pot as it begins to shimmer add your chopped onions and garlic. Once they've browned, add your celery and carrots.
Add your ground beef and pork to the pot, then add your salt, pepper, and parsley leaves, brown the meat well on each side.
Once you've browned it well on each side add your fish sauce to the meat and stir for a few minutes. Now add your white wine to deglaze the pot, stir and allow it to reduce. Once it's reduce add your tomato ingredients, stirring making sure that the sauce doesn't burn. Now add your chicken stock to the dish, and allow the dish to simmer for 1 to 2 hours.
Once the sauce has simmered, add your heavy cream and cheese to the sauce, make sure the heat is not too high. Stir gently for another 15 minutes and then serve over fresh pasta!
Enjoy!
