Ru Yi Cai translates to "as you wish vegetables," and is often served during Chinese New Year. Versions vary, but the common ingredient is soybean sprouts! Check out this classic Chinese New Year recipe, which can be made any time of year as a simple stir-fry.
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.
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.
