Rinse green moong dal with water. Take a large bowl, add the dal and fill it with water. Soak it overnight.
Note: Always choose a large bowl to soak the dal. As it will absorb water and expand. After soaking 1.5 cups of dal, you will get approximately 3-3.5 cups of dal.
In a food processor jar, add moong dal, coriander leaves, mint leaves, onion, garlic, ginger, green chillies, yogurt, besan, cumin seeds, coriander seeds, garam masala, red chilli and salt.
Grind to make a semi-smooth paste.
Let it rest for 15 minutes.
Note: If the mixture feels too wet/moist, add roasted besan and mix well. Here I have added around 1 cup of besan.
Grease your palm with ghee. Take a little dal mixture (around ⅓ cup), flatten it on your palm and add 1 tsp mango pickle at the centre. Seal it. Make all the kebabs in the same manner.
Heat ghee in a pan over medium flame.
Add the kebabs. Shallow fry until both sides are golden in colour.
Serve them hot with green chutney and achari onions.
