Place the sliced chicken in a bowl and mix it with 1 tablespoon of soy sauce. Set aside for 10 minutes. This helps the chicken stay juicy and flavorful.
While the chicken marinates, mix all the sauce ingredients in a small bowl – soy sauce, honey, rice vinegar, cornstarch slurry, and sesame oil. Keep it ready; you’ll need it later.
Heat your wok or pan on high heat and add 1 tablespoon of oil. Once it’s hot, add the marinated chicken slices in a single layer. Sear for 2 minutes on each side until golden brown. Remove from the pan and set aside.
Add another splash of oil to the hot pan. Toss in the garlic, ginger, and onions, letting them sizzle for about 30 seconds. Add the bell peppers and stir-fry for 2-3 minutes until they are slightly tender but still crunchy.
Pour the prepared sauce into the pan with the vegetables, stirring until it thickens. Now, gently fold in the mango chunks and cooked chicken. Toss everything together to coat well in the glossy sauce.
Sprinkle spring onions and sesame seeds over the top for a professional touch. Remove from heat and serve immediately while it’s hot!
