Have some baby bok choy in the fridge... and found this on recipezaar. This was pretty good, but a bit sweet. I think it would be better to keep it simple.

Authentic Asian flavour. Ketjap manis is an Indonesian thick, sweet soy sauce found in the Asian section of most grocery stores. Substitute it with 1 teaspoon low sodium sauce and 1/2 teaspoon sugar.

6 baby bok choy, cut lengthwise in half
1 teaspoon oil
1 teaspoon sesame oil
2 cloves garlic, chopped
1 teaspoon grated gingerroot
1/2 cup chicken stock
1 tablespoon oyster sauce
2 teaspoons ketjap manis (Indonesian sweet soy sauce)
1 tablespoon hoisin sauce
1 teaspoon cornstarch

Blend together: chicken stock, oyster sauce, ketjap manis, hoisin sauce and cornstarch.
Heat both oils in a wok and saute garlic and ginger.
Add bok choy and stir fry 2 minutes.
Stir in liquid ingredients and heat through until thickened and bok choy is tender crisp.
