2 heads head Bok Choy, ends trimmed and cut crosswise into strips and washed if needed
1/2 tsp. salt
1 T butter
toasted sesame seeds for garnish, optional but recommended
Directions
Combine water, soy sauce, sesame oil, and oyster sauce and set aside. Heat wok or heavy frying pan until very hot, about 1-2 minutes, then add oil and heat about 30 seconds more. Add bok choy and salt and stir-fry for 2 minutes. Add soy sauce mixture and butter and stir fry 1-2 minutes more, until bok choy is still slightly crisp, but getting tender. Serve hot, sprinkled with toasted sesame seeds if desired.
