Bolognaise sauce is easy! jus make your own using tinned chopped toms, onion, garlic, herbs, worc's, tabasco (cause i like it spicy) and a bit of tom puree! the only syns you use then is for the tom puree and you only need 1 tablspoon for the whole lot!!
It's trial and error just keep adding things until it tastes how you want it to!
