Drain out the excess water from the soaked Mung Dal. Wash it.
Transfer this dal to a pressure cooker. Add chopped kohlrabi, water and turmeric powder.
Pressure cook it till the dal and kohlrabi become soft.
Meanwhile, prepare the spice mix by combining grated coconut, red chillies and cumin seeds.
Grind them to a fine powder. Keep it aside.
Heat oil in a pan. Add cumin seeds and curry leaves. Fry them on medium heat for 10-12 seconds.
Add asafoetida and chopped onions.
Fry them till the onions turn translucent.
Add this fried mixture as well as the ground spice mix to the cooked lentils.
Add salt. Mix it and boil it on medium heat for 2-3 minutes. Mix with a spatula so that the dal doesn't stick to the base.
Turn off the heat. Garnish with fresh coriander leaves.
Serve hot with steamed rice and ghee.
