To prepare the green moong and vegetable idli, first wash the moong dal and soak in 4 cups water for 2 hours.
Wash urad dal and fenugreek seeds and soak them in sufficient water for 2 hours.
After 2 hours, drain and grind them separately by adding little water.
After grinding, mix both moong dal and urad dal mixture together using a spatula.
Cover and let it ferment overnight or for 6 hours.
After 6 hours, add grated carrot, chopped capsicum and dill leaves and mix well. Add water if needed keeping in mind that the mixture should be thick like idli batter.
Grind coriander, ginger and green chillies by adding 2 tablespoon water to make a thick paste.
Mix this coriander paste into the prepared idli batter.
Add salt and mix well.
The green moong and vegetable idli batter is ready. Let us now make the healthy idlis.
Grease the idli moulds with oil or ghee and pour some the prepared batter into it.
Steam the idlis in an idli steamer and steam for 20 minutes.
After 20 minutes, switch off the gas and let them be in the steamer for 5 more minutes.
Open the idli steamer and de-mould the idlis.
Serve hot with chutney or sambar.
