A nutritious way to thicken casseroles is to use packet potato mix….hhmmmmm
I tested this and managed to create a soup full of little gelatinous balls. Perhaps trying this one with a blender is best.
Have a bonus tip on me:
Brussel sprouts are ‘baby’ cabbages. Don’t overcook them or an unpleasant sulphur smell will develop (not to mention they will taste horrible).
