Mix together the chicken, egg, cornflour, garlic and ginger paste, 2 tsp salt, and enough water so that the chicken pieces are 'coated' with the batter. Leave this for about 1/2 an hour.
Heat the oil and deep-fry the chicken pieces over high heat to begin with and then lower the heat till chicken is cooked through. Drain on absorbent paper.
Heat 2 tbsp of the oil in a wok, add onions and stir-fry over high heat till they are translucent.
Add the green chillies and stir a few times, add the remaining salt, soy sauce, vinegar, and the deep fried chicken.
Mix well, and serve garnished with the green chillies.
