Cabbage is a good source of fibre. Its important to have similar veggies for good bowel movement :) ......I have yet to try making different dishes using cabbage, but let me start with the basic cabbage "ukkeri" or cabbage "sabji" . Its easy to make like any other sabji, .....just cut into small pieces and add the tadka (1 teaspoon oil, mustard seeds, green chilli slit in the middle) and then add cabbage after the mustard seeds splutter. Reduce fire. Do not add water as the water content in the cabbage is sufficient to cook the cabbage. Add salt. Lower the fire to medium. Cover the vessel and let it cook until cabbage becomes tender.
My friend ramya said that she adds coconut gratings and lemon juice at the end. I suggest you can also try that as it would impart a different flavor.
