You need to get garlic. It will taste shite wihtout. I'd also put some tom puree in (ketchup at a pinch!)
start off with cooking your onions, garlic (and finely c hopped celery and carrot if you have it) in some oil, with your herbs, satl and pepper. Add your quorn mince, your tomatoey bits and simmer for AGES. I often put mine into a ovenproof dish at this point and let it cook slowly for a couple of hours. IT really brings out the flavour!
If you've already mixed everything, let it cool and put it in the fridge. Tomorrow, cook some garlic, celery and carrots in oil with S&P then mix it all together and bung in the oven as above,
No good now I know but, for future reference, the Quorn brand of mince isn't very nice -theres a much nicer one that we buy in Waitrose but I think I've seen it in other supermarkets. Its in a bag in the freezer section, has a green front, I think its by RealEat IIRC??
