This recipe for vegetable soup is really quick and easy and is yummy and yet really cheap to make. I just use a bag of chopped veg from the supermarket (they usually only cost £1) but you can use any leftover veg that is lingering in your fridge.
1 packed pre-chopped mixed vegetables (carrots, leeks, onions, swede etc)
1 Tbsp vegetable oil
Handful of parsley
2 pints vegetable stock
Sweat the onion in the vegetable oil in a large lidded saucepan for a couple of minutes. Add the vegetables and cook for 5 minutes. Add the vegetable stock and simmer with the lid on for 20 minutes or until the vegetables are cooked through. Add the parsley and blend with a hand blender until smooth.
