Heat a large frying pan on a medium high heat. Add a little oil and the cabbage and cook, covered with a lid for 7-10 minutes or until cabbage is soft and no longer crunchy. Stir every few minutes and if it starts to burn turn the heat down and add a few tablespoons of water.
When the cabbage is soft turn down the heat to medium low. Add eggs and soy. Stir and cook until eggs are almost set - about 30 seconds.
