Chop the onions, tomatoes, chillies, coriander fine. Chop the bell peppers and spinach if using fine. If you have food processor use it.
In a mixing bowl, mix well the chopped ingredients, besan and rice flour, salt, chilli powder.
Add ½ cup water and make a loose batter. Add more if needed.Your batter should be between dosa batter and neer dosa batter, not too loose and not too thick.
Grease and heat a non-stick pan.
When it is well heated, add the batter in circular motion. You cannot spread the batter much.
Or add the batter in the centre then move it gently to the sides.
Add a few drops of oil on the sides of the dosa. Cover and cook.
You can flip the dosa only when it is well cooked else your dosa will break.
Once you flip it, cook on the other side.
Serve hot with tomato sauce or chutney of your choice.
Notes
In case you are using rava/sooji let the batter sit for about 10 minutes before you start making the pancakes.
Adjust the water after it sits. Remember, you can always add more water.
