First, marinate the chicken in a bowl. Add the diced chicken, orange juice and Mama Lycha soy sauce and mix well.

In another bowl, add the cornstarch, garlic salt, and onion salt. Mix well and add the marinated chicken.

Fry the chicken in a pan with hot oil. 

To make the sauce, put some olive oil in another pan with garlic, dried orange peel, orange marmalade, tomato sauce, oyster sauce, soy sauce, orange juice and some sugar. Mix until it has a thick, jam-like texture and then add the chicken.

Boil the Chao Mein Mama Lycha in a large pot of hot water for 10 minutes.

In another pan, sauté the onion, celery, carrot and cabbage and add the Chao Mein.

Serve some Chao Mein with vegetables on a plate and the orange chicken.
