My friend gave me this recipe. I haven't tried it, but it sounds really good!

1/2 c. sugar
1/8 c. vinegar
1 T. soy sauce
4 tsp. corn starch
2 tsp. sesame oil
2 T. veg. oil
1 T grated orange peel
2 T. chopped scallion

1. Cut chicken breast into 1/2 inch cubes, set aside
2. To make marinade- combine egg white, salt, and sugar in a bowl and stir vigorously until ingredients are thoroughly mixed. Add chicken cubes to marinade and stir to coat well.

Remove chicken from oil with slotted spoon, drain well and set aside. Add fried chicken to pot with heated orange sauce, stir for about 30 seconds, then serve immediately over steamed rice.
