Soak the sabudana in enough water to cover it completely for 3-4 hours or overnight until it becomes soft and fluffy.

Drain the water from the sabudana using a strainer and leave it for 30 minutes to remove any excess water.

In a mixing bowl, add the mashed potatoes, chopped onions, fresh coriander leaves, coarsely ground peanuts, chopped green chilies, ginger paste, red chili powder, and salt to taste. Mix all the ingredients well.

Add the soaked sabudana to the potato mixture and mix it thoroughly.

Take a small portion of the mixture and shape it into a ball. Press it lightly to flatten it into a vada shape.

Heat oil in a deep frying pan on medium flame. Once the oil is hot, carefully slide the vada into the oil.

Fry the vada until it becomes golden brown and crispy from all sides.

Remove the vada from the oil using a slotted spoon and place it on a tissue paper to absorb any excess oil.

Serve the hot and crispy Sabudana Vada with green chutney or tomato ketchup.

Enjoy your delicious Sabudana Vada!
