1. Soak moong dal for 1 hr, drain water and grind it to a coarse paste (don`t grind it to a smooth paste).
2. If you use thick poha/aval, soak for 10 mnts (if you use thin aval then wash it in water, squeeze out the water and use, no need to soak).
3. Meanwhile heat oil in a pan.
4. In a bowl add ground paste of moong dal; to it add aval/ poha, green chillies, palak, coriander, sugar, lemon juice, salt.
5. Mix all the ingredients well, don`t add water.
6. The moisture in moong dal, and poha is good enough for mixing.
7. Make small balls out of it, flatten the balls, and fry the vadas in oil.
8. Enjoy the super crispy vadas with chilli sauce.
