Step 1

Heat 3-4 tablespoons vegetable oil in a wok over high heat, and cook garlic for a few seconds. Add the soybean sprouts, and stir-fry for 30 seconds.

Step 2

Add the leafy greens (tatsoi or Shanghai bok choy), and stir-fry for 1 minute. Add the oyster sauce, salt, sugar, sesame oil, and white pepper. Stir-fry everything together for another 1 to 2 minutes, until vegetables are wilted to your liking. Serve immediately.
