Heat the butter beans in a small pan for 3-4 mins. Remove a quarter of them to a bowl and mash with a fork until smooth and creamy. Stir back into the rest of the beans in the pan with the soft cheese and chives, then heat for a few mins more until warmed through.
Transfer to a small baking dish and sprinkle with breadcrumbs. Drizzle over oil and flash under a hot grill for 1-2 mins until the crumbs are crunchy and golden.
