In a pressure pan, add 1 tbsp of cooking oil. Add cumin seeds. When they start to splutter, add mustard seeds.
Once they splutter, add red chilli and hing. Then add curry leaves. Once the leaves are crispy, add the sliced onion along with slitted chilli.
Add the garlic cloves once the onion becomes translucent. Add chopped tomatoes and cook until tomatoes get mushy.
Add dal along with the water used for soaking. And 1.5 cups additional water.
Add all the spice powders, mix and cook for three whistles.
Once the pressure is down, open the pan and stir the dal so moong dal loses its shape.
Add 1.5 tbsp of ghee and simmer for about 5 mins. Turn off the heat.
Enjoy with hot chapatis.
