Like Lola above i make my own with tinned tomatoes, and add loads veg - onions, peppers, mushrooms to it i usually add a couple tsp Bouillon powder and to liven up a bit i add just a level tsp Pataks curry paste (Madras with chilli & cumin). Yum!
Also try a tblsp red pesto on your cooked pasta - v. nice
I dice red onion, garlic and chilli sweat these off add passta sauce, tomato puree and peppers. I also added oregano (great herb with tomatos. Cook for 20 minutes then blend adding a handful of parsley in at the last minute of cooking.
Can then be used alone or add extra veg for a chunky sauce. Freezable too.
Tin of chopped tomatoes (or 4 or 5 of fresh ones)
1 or 2 cloves of garlic (depending on your taste)
handful of fresh basil (or a teaspoon of dried)
a red pepper
a teaspoon of tomato puree
a splash of lemon juice
salt and pepper
i just shove all that in a blender and its really nice
oregano also works nice in addition to the basil!
in fact.... im going to have pasta tonight, it's made me hungry haha!
For extra va-va-voom in the flavour department, make sure you brown your mince (if using) in small batches in a separate pan so you get good colour on it and the sugars in it start to caramelise. Then de-glaze that pan with a good glug of red wine and add the lot to your sauce. Really boosts the flavour.
A very simple vegetarian pasta sauce is chopping up a load of veggies - carrots, plum tomatoes, red onions, leeks, red peppers and adding enough boiling water (with a spoon of vegetable bouillon) to cover them, then letting them simmer over a low heat for about 2 hours until you have what's basically a thick vegetable jam. Incredibly sweet and lusicious, really lovely with pasta.
