Is it a big batch? I've only cooked it twice - once on the cooker top and once in the slow cooker.
The batch made on the cooker top reduced a lot to leave a very chunky tasty stew type soup which worked perfect left lumpy with pasta or sweet potato wedges.
The batch made in the slow cooker definitely stayed like more of a soup - after a couple of bowls of chunky soup I blended it down to a smooth variety.
Personally I didn't use this as a pasta sauce but I have definitely heard of others using it as sauce substitute with pasta, chilli etc.
Yummy!
