In a small bowl, mix together 2 tablespoons of the chicken broth, soy sauce, oyster sauce, and hoisin sauce. Set aside.
In another small bowl, whisk together 2 tablespoons of the chicken broth and cornstarch. Set aside.
In a large skillet or stir-fry pan on high heat, bring the remaining chicken broth to a boil. Add the prepared green beans. Stirring often, cook until the beans are crisp tender, about 3-4 minutes. Transfer to a bowl, and set aside.
Wipe the skillet clean with a paper towel. Add oil and heat over high heat.
Add the chicken to the skillet and stir-fry until they are cooked through and no longer pink, about 5-7 minutes. Season with Asian Seasoning or salt and black pepper.
Add minced garlic and ginger to the skillet and cook for about 30 seconds, or until fragrant.
Add the green beans to the skillet, and cook 1 minute.
Pour the soy sauce mixture over the chicken and beans, and cook for 30 seconds.
Pour the cornstarch mixture into the skillet, and cook an additional minute or until the sauce has thickened slightly.
If desired, garnish with sliced green onions or sesame seeds. Serve over rice, noodles, or zoodles.
