Mix in the parmesan cheese to the  beef mince 

Mix in the herbs to the mince  (Can also use mixed or Italian herbs if you do not have all the individual herbs)

Mix in Salt and pepper

Mix by hand folding back and forth making sure they are well mixed - see the video and photos

Make the meatballs - you can use an ice cream scoop to get them all the same size

Slice mushrooms 

Dice carrot, celery, garlic, and onion

Put in the Instant Pot the vegetables and the bacon at the same time and gently cook (sweat) the vegetables

Add tomato paste and mix with the cooked vegetables

Then add the wine and mix again 

Then add the crushed tomatoes, beef stock, Lea - Perrins, paprika, sugar, and mix

If you want you can add a little chilli or cayenne pepper to taste

Put the Meat balls in the mix and gently stir so they are well wet

Put on the lid and cook for 15 mins high pressure 10 mins natural release

After cooking taste the tomato sauce and add salt, pepper, and if necessary a little more sugar if the taste is too tart. (Tomatoes can cause the sauce to be a little tart or sour and just a very small amount of sugar fixes this.)
