Salads made from dried beans soaked overnight and then boiled mixed up with chopped raw onions are very delicious but they need some forethought. If you are in a rush you could always keep some tins of beans in your cupboard to make this useful salad. You can use either raw red cabbage or raw onion.
Take off the outer leaves of the red cabbage and chop into fine small pieces. Put into a salad bowl with the drained tinned beans. Toss with a strongly seasoned oil and vinegar dressing.
