Add spring onion, capsicum, refined flour and one-fourth cup of cornflour. Mix thoroughly. Shape into lemon sized balls.
Heat sufficient oil in a wok and deep-fry vegetable balls in small batches for three to four minutes on medium heat or until golden brown. Drain on absorbent paper.
Heat two tablespoons of oil in a wok or a pan and stir fry the ginger and garlic half a minute. Add the celery, green chillies and stir-fry for half a minute more.
Add soy sauce, sugar, MSG and salt. Stir in vegetable stock and bring to a boil. Stir in cornflour mixture and cook for a couple of minutes or until the sauce starts to thicken, stirring continuously.
Add the fried vegetable balls, vinegar and mix well. Serve hot, garnished with the reserved spring onion greens
If you want to serve it dry without the sauce, reduce the stock to one cup and cornflour in the sauce to one and a half tablespoons only.
