Wash the sabudana with water in a sieve. Soak the washed sabudana in 1 cup water for 6-8 hours. To check if the sabudana is soaked, press one pearl in between your fingers and it should mash easily.
To make the sabudana mixture, mash potatoes and add green chillies, peanuts, curry leaves, coriander, jeera powder, sugar, chilli powder, lime juice, salt and soaked sabudana. Mix this well.
Next make the filling by adding paneer, jeera powder, chilli powder, coriander and salt to another bowl. Mash and mix it well with your hands. Form the paneer mixture into small lime sized balls.
To make the sabudana vada bombs, wet your palms with water. Take a golf ball sized sabudana mixture on your palm and flatten it. Place a ball of paneer mixture in the center and press the sabudana mixture around the sides so that it covers the ball on all sides. Take a small piece of sabudana mixture and place it on top to cover the paneer on all sides and form the sabudana vada. Repeat this till all the sabudana vadas are formed.
Fry in medium hot oil till the vadas are golden brown on all sides. Serve immediately.
