Soak channa dal for atleasst 1 hour in room temperature or luke warm water.
Drain the water.
Grind the channa dal, green chillies and ginger to a coarse paste. (One can use grated or chopped ginger too, I prefer to blend it).
Use minimum water while grinding.
In a wide bowl, add the coarse paste, salt, sesame seeds and mix well.
Line a baking tray with parchment paper and preheat the oven to 180 Deg C.
Take a tablespoon of batter in your hand and form in the shape of a flat pattice.
Line it on a parchment paper.
Bake in the oven for 10 mins, then brush some oil on the top.
Bake again for 10-15 mins.
Flip and brush oil on the bottom and let it bake again for 15 mins.
Baking time may vary, but it generally takes around 45-50 minutes.
When you feel it is done, for the last 5 mins you can broil the top of the vada's to give it the golden colour.
Alternatively one can fry them on medium until golden brown.
