Heat the oil in a kadai or wok on medium heat, then add the mustard seeds and cook until they start to pop.
Add the green chilli, urad dal and curry leaves. Fry, stirring frequently, for two minutes or until the dal is golden brown.
Add the cabbage and salt, mix well and cook on medium heat for around 5-7 minutes, stirring frequently. Add a tablespoon of water if the cabbage starts to stick to the pan. You want the cabbage just cooked and retaining some crunch.
to serve
Remove from the heat and stir the grated coconut through. Serve.
notes
A small cabbage weighs approximately 800g.
The cooking time of 5-7 minutes will cook the cabbage, but still retain texture and crunch.
