In a small bowl mix together the oyster sauce, sugar and soy sauce, set aside.
Heat oil in a wok over medium-high heat, add garlic and stir for 20 seconds.
Next, add in the green beans and stir until they begin to soften, about 5 minutes.
Pour in the sauce and cook until the green beans have attained your desired degree of doneness.
Finally serve with a drizzle of sesame oil and enjoy!
Notes
Store any leftovers of these Chinese Green Beans in an airtight container in your fridge for 3-4 days. To reheat you can do so in a skillet on the stovetop or in the microwave until everything has warmed through.Freezing is not recommended because the beans will become watery and lose their crisp texture.
