Basically this is my Spanish version of one of those old British favourites – sausage & beans. The main player the chorizo, adds a real depth to the dish. Its spice, rich oiliness and colour from the infused paprika, soaks into the butter beans, whilst the caramelised onions and peppers combine to unite all the flavours. This takes no times to cook and works great as a tapas package if you are entertaining. Try it with Pulpo a la gallego a fantastic Spanish octopus recipe.
