Combine the chicken with the other marinade ingredients thoroughly and place it in a bowl. Refrigerate the bowl while you prepare the vegetables and sauce.
Before cooking, preheat the air fryer at 370°F for 2-3 minutes. Then, add the marinated chicken and cook for approximately 3 minutes on each side, until it turns golden brown and reaches an internal temperature of 165°F.
In a separate skillet, heat 1-2 tablespoons of oil, then add the chopped green beans. Sauté them for 2 minutes. Next, incorporate the thinly sliced onions with the green beans, adding a pinch of salt, and continue to sauté until the onions are translucent, about 3 more minutes.
Finally, bring the sauce and cooked chicken into the skillet, stirring everything together on high heat for about 30 seconds to combine the flavors.
Serve this delightful mixture over rice or rice noodles, garnished with sesame seeds for an extra touch of flavor and texture. Enjoy your meal!
