In a small bowl, whisk together the soy sauce, oyster sauce, cornstarch, and chicken broth. Set aside.
In a large skillet or wok, heat the vegetable oil over medium-high heat. Add the sliced pork and cook until browned, about 3-4 minutes. Remove the pork from the skillet and set aside.
In the same skillet, add the minced garlic and cook for 1 minute until fragrant. Add the green beans and cook for 4-5 minutes until crisp-tender.
Return the cooked pork to the skillet and pour in the sauce mixture. Stir well and cook for another 2-3 minutes until the sauce thickens.
Serve the pork and green bean sauté hot and enjoy!
