In a large pot, add a knob of butter and a drizzle of olive oil.

Add your italian sofrito - carrots, celery, and onion, finely diced

Season with Salt, Pepper, and Italian Seasoning. Let the vegetables sweat and onions become translucent.

Add tomato paste and mix to cook through for a few minutes.

Add red wine and cook out till you no longer smell alcohol

Add the ground beef and sausage removed from casing. Stir everything and cook through till all of the meat has turned a brownish color. Spoon out any excess fat or oil if necessary.

Add Passata to the meat mixture and bring it to a boil then lower the heat to reduce the sauce. This can take up to three to four hours. Stir it every so often and ladle out any excess oil as seen when it floats to the top.

Once sauce is ready, add a little more butter, cheese and a splash of milk is optional.
