Chicken Broccoli Ca - Unieng's Stir fry

This recipe is an Indonesian-Chinese Stir Fry recipe and I got it from All Recipes. I've never cooked with Bok Choy before, but I have to say that it was really good and made the meal!
Serve up with some brown or white rice and dinner is ready!

You will need:

12 ounces boneless, skinless chicken

breast halves, cut into bite-sized pieces

1 tablespoon oyster sauce

2 tablespoons dark soy sauce

3 tablespoons vegetable oil

2 cloves garlic, chopped

1 large onion, cut into rings

1/2 cup water

1 teaspoon ground black pepper

1 teaspoon white sugar

1/2 medium head bok choy, chopped

1 small head broccoli, chopped

1 tablespoon cornstarch, mixed with

equal parts water

To Make:

               In a large bowl, combine chicken, oyster sauce and soy sauce. Set aside for 15 minutes.

               Heat oil in a wok or large heavy skillet over medium heat. Saute garlic and onion until soft and translucent. Increase heat to high. Add chicken and marinade, then stir-fry until light golden brown, about 10 minutes. Stir in water, pepper and sugar. Add bok choy and broccoli, and cook stirring until soft, about 10 minutes. Pour in the cornstarch mixture, and cook until sauce is thickened, about 5 minutes.
