Roasted Brussel Sprout Soup | Slimming World Friendly Soup

    This unofficial Slimming World friendly Roasted Brussel Sprout Soup is healthy, delicious and full of flavour. It is so quick and easy to make too.. do your kids hate sprouts? Mine do but they love this soup! Little weirdos… Give it a try! 

    This soup is like Christmas in a bowl.. other than the fact it’s actually February! I love sprouts, I am literally the only one who eats them whole in this house! Mr Fatgirlskinny literally hates them and the kids are not far behind! When I served this little beauty up I didn’t tell them what it was (they are kinda used to that).. But it worked, it got them to try and it and they all agreed it was delicious. I gave myself a high five by the way… because that’s just what I do! Honestly though, when you have 1 kiddo who asks for raw pepper, carrot etc from the fridge as a snack and another who will only snack on biscuits or chocolate you have to take your wins where you can! 

    Anyway enough waffling on, give this soup a try I promise you won’t be disappointed!

    So let’s talk about this soup…. it’s creamy, thick, rich, and super comforting
