If available, use a food processor to finely mince the chicken breasts (or finely mince by hand). Add the prepared vegetables to the minced chicken, mixing well.
Shape into 1-inch balls and roll in flour to coat. Heat 1/4-inch oil in a large frying pan and fry balls until golden. Drain on paper towels and serve hot with Plum sauce or Hoisin sauce.
