Wash and soak white channa overnight or 6 –8 hrs ( add a pinch of cooking soda while soaking which makes the channa soft ). Drain the soaked water completely and wash again to remove the soda completely.
Pressure cook it adding the required water and salt. Drain the excess water .
In a kadai , heat oil and temper all the items given above in the same order.
Add the cooked channa and mix well. Finally add the grated coconut, toss well.

Notes
Adding cooking soda while soaking chana is purely optional. But it makes the chana soft after cooking.
If you add cooking soda, drain the soaked water and wash again before cooking it. Add salt while cooking. Suppose if you forget to add salt, add it immediately after you pressure cook keeping little water. Salt gets absorbed by chana.
Adding grated ginger is also optional but it helps for digestion of sundal. Add hing generously.
You can add more coconut to make the sundal tastier.
Add lemon juice and coriander leaves as per your need.
If you use black chana, replace red chillies by green chillies. Roast chana in little oil till you get nice aroma and cracking sound. Pressure cook it immediately. No need of soaking.
But the channa will not be much soft. If you want it soft, add a pinch of cooking soda while you pressure cook it.
For variations, you can coarse grind the grated coconut, chillies and add to channa. Saute for few minutes and add lime juice and coriander leaves at the end.
