Brocolli & Cauliflower soup

Brocolli and Cauliflower soup - serves 2-3

1 brocolli, cut up
1 cauliflower, cut up
1 potato peeled and diced (this thickens it but can be removed for a thinner soup or if on a red day)
1 onion, diced
1 veg stock cube
Place all the vegetables into a pan
Cover with boiling water so it just covers the veg.
Place the veg stock cube into a jug and add just enough boiling water to dissolve it then add to the pan of veg
Add salt and pepper
Boil for 30-40 minutes until all the vegetables are soft
Blend and serve*
* I sometimes add a splash of milk (1 syn worth or some from healthy extra a) to make it creamy - very nice!
