Coming back on the recipe I am sharing here, I learnt it from my mom. Its very simple and easy. Only tricky part is the batter. If that is done correctly, you are all set to make it. Here is the recipe for "Moong Dal Chilla".
This recipe makes 6 chilla.
1 cup washed split moong dal
1 onion chopped finely.
1 large tomato chopped finely.
½ cup bell pepper chopped finely.
¼ cup coriander leaves chopped finely.
2 green chilies deseeded and chopped finely.
¼ turmeric powder.
½ red chilli powder.
1 ¼ cup water.
1 tsp salt or to taste.
Oil for shallow frying.
Soak the moong dal for 2-3 hours. It will double in its volume. Drain off the water and add 1 ¼ cup of fresh water and churn in the mixer to form a liquid paste. Add turmeric powder and red chilli powder. Add the salt just before making the 'Chilla'. The batter should have a dropping consistency just like dosa.
Keep the chopped veggies aside.
When done transfer it on a paper towel. Continue with the rest of the batter.
