1 lb baby bok choy, sliced in half & washed
2 T sesame seeds
1 tsp sesame oil
1 T olive oil
2-3 tsp chili flakes

Heat a large nonstick skillet to medium high heat. Combine the oils and heat through. Add the bok choy. When green part is wilted but firm white part is still crunchy, add the chili flakes. When the white part starts to near translucency, add the sesame seeds and cook for 1-2 minutes. Be sure to move them around a bit as they cook to prevent the greens from wilting.

You could also chop the greens off, chiffonade them, and slice the stalks of the bok choy, cooking them first and adding the greens at the end.
