In a bowl, mix mashed potatoes, cornflour, herbs, salt, and black pepper.
Take a small portion of the mixture and place grated cheese in the center.
Shape into small balls and coat with bread crumbs.
Heat oil in a deep pan on medium flame.
Deep fry the cheese balls until golden brown and crispy.
Remove and place on tissue paper to absorb extra oil.
Serve hot with ketchup or mayonnaise dip.
