Broccoli and Stilton Soup

2 onions, chopped
1 broccoli, chopped
1 tin beans (I used flageolet, but only because I couldn't find any cannellini in the cupboard)
20g butter
600ml vegetable stock
60g stilton

Heat the butter in a pan and brown the onion for 2 minutes. Add the broccoli for 2 minutes. Add the vegetable stock and beans, then boil for 20 minutes.

Blend, add water if necessary, and stir in the stilton until melted. Season and serve.

Serves 4.
