Mix all the ingredients for the sauce in a bowl until the cornflour is thoroughly blended. Set aside. Spray a wok or deep frying pan with low calorie cooking spray and place over a high heat.
When it is very hot, add the chicken and stir-fry for 6-7 minutes until the chicken is cooked through. Add the garlic, spring onions and peppers and stir-fry for 2 minutes.
