Heat a kadai, add besan, 1 tbsp oil, 1/4th tsp haldi, 1/4th tsp hing, and salt.
Mix well, cook till the flour starts to turn dark in color, and then transfer to a bowl.
Add 1 tbsp oil in the same kadai, and when the oil heats up, add mustard and cumin seeds.
Add 1/4th tsp of hing and haldi each when the seeds start to splutter.
Add green chilies and raw papaya, and mix well.
Add salt and sauté for 3-4 minutes. (Remember we had added salt in besan as well, so add salt accordingly.)
Cover and cook for 2-3 minutes.
Add roasted besan and sauté till the flour soaks up the moisture.
Serve as an accompaniment with sabzi-roti. (Traditionally, papaya sambharo is served along with fafda.)
