I used Electric pressure cooker for it and I am going to tell you the same recipe here. You can use a regular kadai on stove and cover and cook it. People can avoid Onion and garlic if they dont like it.
Gongura leaves - 1/2 cup
Mint leaves - 1/4 cup or even less
Moong dal - 1/2 cup
Green chillies - 3 (you can use red chilli powder also)
Salt to taste - I used 1 and 1/2 spoon
Oil - 2 table spoons
Turmeric - pinch/less than 1/2 tea spoon
Cumin seeds - 1/2 tea spoon
Onions - 1 medium sized, finely chopped
Garlic - 2-3 pods peeled and chopped.
Method of preparation
1. Connect the electric pressure cooker to the socket and click the "Menu" button thrice to get to "Browning" mode. Click "Start".
2. Add oil and a minute later add cumin. Now add garlic and green chillies, stir it. Add onions to it a minute later and then let it saute for a minute. Now add washed gongura leaves, mint leaves, moong dal, turmeric, red chilli powder (if neccessary). Add 2-3 cups of water according to your desire.
3. Change the mode of the cooker to "High Pressure" by clicking "Cancel" to cancel current mode and then hitting "Menu" twice. Now click on time twice to increase it to 3 minutes and then click start. When the water starts heating up, add salt to it, mix it and then cover it up. Your dal is ready in 5 minutes or so. After the pressure is down, transfer the contents to a serving bowl.
