Coat each chicken piece in tapioca starch.
In a deep wok/pan over medium-high heat, heat up the neutral oil until it reaches 350°F/180°C.
Fry the chicken for 5 minutes, or until golden brown and the chicken is cooked through. Remove, and deep fry for a second time for an extra 2 to 3 minutes. This makes it even crispier! Remove and place the chicken on a wire rack.
Using a clean wok, heat up 1 tbsp of neutral oil. Bloom the garlic and onion and then add in the diced red bell pepper and jalapeño. Quickly stir fry. Pour in the sauce mixture and bring to a boil. Keep stirring until the sauce thickens.
Add in the fried chicken and toss to let the sauce coat.
Plate and top with toasted sesame seeds. Enjoy!
