For preparing vada paavo, mix gram flour and salt with required water to make a thick paste. Keep it aside.

Add ginger, garlic, chilly paste and required salt to the mashed potatoes. Mix well.

Splutter mustard seeds in oil. Add in curry leaves, turmeric powder and the mashed potato mixture. Mix well.

Make lemon sized balls out of it. Dip each ball in gram flour paste and deep fry it in oil.

Take the bun and slice it in the middle without separating it completely.

Put 1 tsp of each chutney inside the bun and 1 ball of vada. Close the bun and insert a toothpick to fix the bun.

Vada paavo is ready. Serve immediately.
