In a small bowl, whisk together the vegetable oil, soy sauce, oyster sauce, sesame oil, and sugar. Set aside.
2 tablespoons vegetable oil, 2 tablespoons soy sauce, 2 tablespoons oyster sauce, 1 tablespoon sesame oil, 1 teaspoon sugar
Bring a pot of water to a boil. Add the noodles and cook for 20–30 seconds, just until loosened. Drain well and toss with a little oil to prevent sticking.
8 ounces chow mein noodles
Heat a large skillet or wok over high heat. Add a bit of oil, then stir-fry the onion, cabbage, celery, and garlic for about 1 minute, until slightly softened but still crisp.
2 cups cabbage, 1 cup celery, ½ cup onion, 2 garlic cloves
Push the vegetables to one side of the pan. Add the noodles and pour in the prepared sauce.
In a small bowl, mix the chicken broth and cornstarch, then add it to the pan.
¼ cup chicken broth, ½ tablespoon cornstarch
Toss everything together until well coated and heated through. The sauce should lightly thicken and coat the noodles.
Garnish with chopped green onions and serve immediately.
