Whisk together soy sauce, oyster sauce, honey, and sesame oil in a small bowl; set aside.
Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat until shimmering.
Add the chicken strips in a single layer and sear until cooked through and golden brown, about 5 minutes. Remove chicken and set aside on a plate.
Add the remaining 1 tablespoon of oil to the same pan. Add the green beans and stir-fry for 3 to 4 minutes until bright green and slightly blistered.
Add the minced garlic and ginger to the pan and cook for 30 seconds until fragrant.
Return the cooked chicken to the pan and pour the sauce mixture over the ingredients.
Stir in the cornstarch slurry and toss constantly for 1 minute until the sauce thickens and coats the chicken and beans evenly.
Remove from heat and serve immediately over steamed rice or noodles.
