Sweet Potato, Carrot & Red Lentil Soup

It's another hottie outside so I'm staying in.  I like to batch cook and the last couple of days i've had a craving for home made soup, so I've made a huge batch of Sweet Potato, Carrot and Red Lentil Soup.  (If you're on Slimming World, this is ideal as it's free).

When I make a soup like this, I don't weigh & measure my ingredients, I just throw them in and see what I get.  So the recipe below is quite loose.

Onions, Celery and garlic chopped/crushed and fried using Frylite.
Chop the sweet potato and the carrots and add to a pan of boiling water with a chicken or beef stock cube in it.  Then add the fried onion, celery & garlic mix.  I usually add a squirt of tomato puree and mixed herbs and season.  Then add about half a bag of red lentils.  Bring to the boil then turn down to simmer.  

I make a large batch and then freeze it in portion sizes.
