Verzada (sausage and cabbage casserole)

Shred the cabbage coarsely, wash thoroughly and drain.

Heat the butter in a heavy-based saucepan. Add the belly pork or bacon and fry until the fat begins to run.

Add the onion and fry until soft, but not brown. Add the cabbage and stir until well coated in the fat. Cook over a moderate heat until the cabbage begins to brown.

Sprinkle with the vinegar and season with salt. Arrange the sausages on top, cover and simmer over a gentle heat for 40 minutes to 1 hour.
