Heat oil in a wide heavy bottom pan.
Once hot, add mustard seeds, once they start to pop, add asafetida.
Add chopped Cabbage and 1 tsp of salt. Mix well, cover and cook on medium heat until Cabbage is half way cooked. Mix 2-3 times during this step to ensure Cabbage does not start to burn.
Uncover and add all the spices along with 1 tsp of salt. Mix well.
Add frozen peas (let them sit in tap hot water for 8-10 minutes. Drain water out before using it). Mix well, cover and cook for 3-4 minutes or until cabbage is ¾ the way cooked, I like to leave it just a little crunchy!
Uncover, mix well and turn the heat off. Simply serve it with phulka rotli, kadhi, mori dal and bhaat!
