Had a cauliflower that needed using up and made this up using other ingredients I had in the fridge. Worked out to be really tasty and will now be a staple soup. So very easy to make, so that's another bonus!
To each portion (should make four to six bowls) add some crumbled blue cheese in and stir until melted. Equally nice with low fat cream cheese with garlic and herb swirled in. Haven't tried with Cheddar but imagine that would also be nice but all I can say made once and will certainly be making it again!
