In a large bowl, combine chicken breast with egg white and cornstarch, then mix well. Cover and refrigerate for 10 minutes.
For the sauce, get a frying pan and put-in together all the ingredients: orange juice, soy sauce, sugar, sesame oil, salt and pepper, garlic, ginger and water.
Turn on the heat and cook for 5 minutes.
Then, gradually pour-in the melted cornstarch into the pan and simmer for another 5 minutes. Wait until the sauce gets thick. Set aside.
In another frying pan, fry the seasoned chicken until golden brown.
Then, pour-in the cooked sauce into the pan with chicken and simmer for about 2-3 minutes.
Serve while hot! Enjoy.
