This makes enough for four or you can let it cool, keep in the fridge and heat up a bowlful at a time.
Ingredients (for four):
Take your onions and potatoes and chop small. Heat the oil in a pan and sweat the veg until soft. Add the broccoli and sweat a minute or two more. Add the stock, cook for 20-30 minutes until everything is soft. Blend until smooth. Add the milk and cheese, heat through until melted and just on the simmer again. Take off the heat, and adjust the seasoning.
