Peel and finely dice the onion and fry in olive oil until golden brown. Add the vegetable stock and the soup seasoning and simmer.
In a saucepan, slowly heat the cream and the processed cheese, stirring, until the cheese has melted. Warning: not too hot, burns quickly.
Wash and finely chop the wild garlic. Add the cheese-cream mixture and the wild garlic to the soup. Save some wild garlic to sprinkle. Bring to the boil and then puree. Season to taste with salt and pepper, possibly chilli.
