This is something very simple, and takes no more than 10 minutes of preparation and cooking.
Ingredients:
About 4 cups of baby bok choy leaves.
1 tsp olive oil
1 tbsp peanut butter
1 tsp sesame seeds
1 tbsp any stir fry sauce
1 tsp of chilli oil.
2 tbsp water
Combine everything but the bok choy in a wok. Turn the heat to maximum. Wash the baby bok choy and separate the leaves, then add them to the wok. Stir for about 5 minutes. You are all done. I threw the sauce away since it is kinda oily, and there is enough of the taste soaked in the bok choy in any case.
