Pressure cook the dal on medium heat with 2 cups of water (I cook till the vent goes off 4 times and the dal is well cooked.) Shut the gas off and set aside.
On medium heat, add oil to a wok or kadhai followed by tomatoes and green chillies. Fry the tomato puree until the oil separates out or when the tomato puree loses the moisture and has thick gravy like appearance.
Add the pressure cooked dal,salt, turmeric powder and mix well. Simmer it for 10 minutes. Add water (if needed) to get the dal to a consistency you like.
Heat ghee in a separate pan and add cumin seeds and when they start to sputter add minced garlic cloves. Fry for around 10-20 seconds and then add this to the dal in the cooker.
Garnish it with coriander leaves before serving.
