Pre-heat 1 tbsp oil and fry the Quorn pieces for a few minutes until beginning to colour, put to one side.
In a deep pan, heat the oil and add the onion. Fry for 3 minutes, then add the garlic, spices and cauliflower florets, mixing well and ensuring the cauliflower is evenly coated.
Fry for a further 3 minutes, then add the stock. Bring to the boil, before leaving to simmer for 10 minutes.
Remove from the heat and blend the soup using a hand blender until smooth.
Return the soup to the heat and add the diced potatoes, allowing to simmer for 15 minutes, or until tender.
In the final 5 minutes, add the Quorn Pieces. Allow to cook through thoroughly, stir in the cream and coriander. Season to taste. Serve hot and garnish with the chopped coriander and a sprinkling of smoked paprika.
