Using the same pan used for frying the chicken earlier, reduce the oil to about 2 tbsp and then add 3 minced garlic cloves and 1/2 tsp of grated ginger; stir fry for 30 seconds or until fragrant.
Add the vegetables: chopped celery sticks, chopped red bell pepper, baby corn, and broccoli florets.
Cook while stirring for 5 minutes or until all the vegetables are slightly wilted.
Next, season with a little bit of salt and 1/4 tsp of chili flakes. Stir to combine and return the fried chicken into the pan.
Add the prepared Huna sauce into the pan and stir to combine and coat with all the ingredients and the fried chicken pieces.
Cover and cook on low heat for 3 to 5 minutes to reheat the chicken and also thicken the sauce.
You can turn off the heat after cooking for 5 minutes. Your easy Hunan chicken is ready; you can garnish with some sesame seeds and serve with boiled rice.
