I make my spag bol from scratch

I use:
onion
mince (obviously)
tomato paste
tomato sauce
sweet chilli sauce
worchestershire sauce
bbq sauce (just splashes of each sauce)
grated carrot and zucchini and pumpkin
mixed herbs

Yummo!!!
That's pretty much what I use in mine, give or take on the vegies some times. Always add the extra sauces for flavour. And I looooooooove it with Angel Hair pasta, that stuff is just the best. DH is actually cooking it now as I take some time out.
