You can buy pre chopped bags of carrots and suede to save time.
This was fantastic. I used ready made soup mix with chopped swede, onion, carrot with parsley. I like my lentil soup chunky so didn't blend it. I also threw in some frozen petit pois an hour before serving. Next time I will put some cooked gammon in it if I want a meatier soup but love this at it is. - 11 Feb 2016
This is delicious. I'm into slow cooker use this time of year and bought one of those plastic boxes of mixed root veg from the local market - for about 1 euro 30. I already had the lentils and stock cubes but the veg pack had onion, potato, carrots, small swede, a big parsnip AND a bundle of herbs (bay leaf, parsley, rosemary and sage). I cooked it as Poppy said and blended to make it fairly smooth. It was DElish with a sprinkle of grated cheese and a baguette. Will try it next time with a tin of chopped tomatoes as part of the water content. I removed the sage from the herb bundle because I thought it might overpower the finished soup. - 26 Jan 2016
