Mashed butter beans

Got this recipe from the Hairy Bikers and although I have changed it slightly it's a delicious low card version of mashed potato and dead east too, highly recommended!

Ingredients
A dash of olive oil
1 small red onion2 medium garlic cloves

1 400g can butter beans
5 large sage leaves chopped

A dash of double cream
Salt and pepper to taste

Method
Heat the oil in a frying pan that will hold the onions and butter beans comfortably.  Peel and chop the red onion and crush the garlic while the oil heats, then add them to the pan and fry over a medium heat until softened and starting to brown slightly.  Drain and add the butter beans, add the sage leaves and the double cream and stir well to heat through.  Mash them lightly with a potato masher, adjust the seasoning to taste and serve.
