Mix the egg white, cornstarch, salt and ginger in a bowl, add the chicken strips and leave to marinate in the refrigerator for about 30 minutes (or, if you`re in a hurry, just bread the fillets, it tastes just as great!).
Heat the oil in a wok or a large frying pan and fry the chicken strips until they are cooked, turning over and over so that they do not turn brown.
Arrange the chicken strips on a plate and cover.
For the sauce, mix the cornstarch with the water, then bring all the ingredients to a boil in a wok and simmer until the sauce thickens.
Pour the sauce over the meat or serve separately, as desired.
