ive used a slow cooker for years but never used a recipe for anything! i find whatever i chuck in is wonderful. for a veg soup i would use: swede, carrot, onion, celery, turnip, tin of tomatoes maybe, handful frozen peas. anything i have in really. Add some herbs and garlic, vege stock cube and thicken with cornflour. cut everything to a similar size and leave on while at work then hey presto. may be left chunky or blended and you can spoon in some cream when serving for something bit more special or add dumplings for kinda vege casserole! the variations are endless.
