Wash and soak the green moong dal in plenty of water for 8 hours or overnight. After 8 hours, rinse the dal and drain the water completely.
Add the dal to a blender. Add the green chili, ginger and cumin seeds.
Add ¾th cup of water and grind the dal. It should be ground well but doesn’t have to be super smooth.
In a plate add finely chopped onion, grated carrot and chopped coriander. Mix it well.
Transfer the batter to a large bowl and add the onion mixture. Add salt and mix the batter. If you feel the batter is too thick add some water, not too much. I added ¼th cup of water to the batter.
Preheat the waffle maker and spray some oil. To my round waffle maker I added about ¾th cup of the batter in the middle. Using a spatula spread the batter to fill the cavities and drizzle some oil.
Cook the waffle as per instructions. You can select the desired level depending on your preference. It may take 3-4 minutes for the waffle to cook. Once done, gently remove the waffle with a spatula and serve it with chutney.
