In a large saucepan over medium/low heat, add the olive oil and onion. Sauté for around 3 minutes. Season with a generous pinch of salt and pepper.
Next, add the carrot, aubergine, and celery into the pan. Continue to fry for around 5 minutes, stirring occasionally. Season with salt and pepper.
When the aubergine begins to soften and the carrot starts to soften, add the tomato puree, garlic, fresh thyme, and mixed herbs. Fry for a couple of minutes to release the flavours.
Add the plum tomatoes, stock, and Quorn mince to the pan. Use your spatula to break the plum tomatoes apart.
Stir to combine and cover with a lid. Leave to simmer for 20-30 minutes, stirring occasionally.
Meanwhile, cook the rigatoni until two minutes shy of the packet instructions. Reserve some pasta water before draining.
Add the rigatoni into the bolognese with a splash of pasta water and continue to cook until al dente. Serve with an optional sprinkle of vegetarian parmesan and enjoy!
