Steam the Asian greens (bok choy and Chinese broccoli) for 2-3 minutes in a steamer or blanch them by placing them in a heat proof bowl and cover them with boiling water for 2-3 minutes. Drain.
Combine the dressing ingredients (garlic, ginger, soy sauce, oyster sauce, and peanut oil) in a jar or small container and shake or stir well to combine. Toss the warm, drained vegetables in the dressing and serve.
This recipe is a fantastic accompaniment to steamed fish or poached chicken breast and a small serving of brown or basmati rice.
