For The Potato Balls
In a bowl, add mashed potatoes and eggs and stir until well combined.
Stir in flour, salt and Panko Crumbs and gently mix until well combined.
Roll the mixture into balls that are about 1½ inches in size. Put the balls on a baking sheet and let them chill for around 10 minutes. This will make the balls firmer, so the filling doesn't come out when you fry them.
In a deep fryer or a pan, Heat oil over to 375°F. Add potato balls to the hot oil and cook for about 3 minutes or until golden brown.
Take out the Potato Balls from the hot oil and put them on paper towels. Sprinkle some salt on them. Serve the Potato Balls while they are still warm. Enjoy!
