Dice onion and finely chop the garlic cloves. Using a large frying pan, sauté the onion and garlic with olive oil over a medium heat until the onion is translucent.
If using the bacon, dice and add after 3 – 4 minutes, cooking until lightly crispy.
Add the pork mince meat and break up with a spatula or spoon. Cook over medium heat for approx 10 minutes or until there is no visible pink bits.
Add in the canned tomatoes, red wine, tomato paste, basil and oregano. If you are using them, also add the BBQ sauce and balsamic vinegar.
Stir to thoroughly combine and taste for seasoning, add salt and pepper as required. Usually if you have used the bacon and stock paste, it will be salty enough.
Turn heat to low and simmer for approx 20 – 30 minutes until thickened. You want a reasonably dry sauce as the zucchini lets out a bit of water as you eat.
While it is simmering, spiralise your zucchini and shave your parmesan ready for serving.
Serve the bolognaise over zucchini, topped with cheese.
