For the Tempering
In a bowl, take the carrot, cabbage, soaked dal, lemon juice, coconut and salt. Mix well.
In a heated pan, dry roast the mustard seeds, curry leaves and red chilli (if you are using it). Turn off the heat and add asafoetida. Add this tempering to the rest of the ingredients and mix. Garnish with coriander leaves. Serve.
