Heat the oil in a large saucepan. Add the chopped onion and saute for 5 mins or so until it has softened. Add the cauliflower, potato, stock, milk and some salt and pepper.
Bring the mixture to the boil and then reduce to a simmer. Place the lid on the pan and simmer for 30 minutes until the cauliflower and potato are soft. Remove from the heat.
Use a hand held immersion blender to blend into a smooth soup. Stir in the grated cheese until melted. Taste and add more seasoning if desired.
Serve topped with a few croutons and a pinch of grated cheese (optional).
