Begin by stir frying the chicken along with the egg and a pinch of salt.
In a separate bowl, combine the tempura mix (or a quarter cup of flour and cornstarch) with the egg and salt.
To prepare the sauce, mix together the ketchup, rice vinegar, brown sugar, honey, minced garlic, sesame oil, soy sauce, cornstarch, and sesame seeds.
Heat oil to 340°F and fry the chicken in batches for about 6 minutes each.
Once the first batch is done, remove it from the oil and add the second batch.
Chop the green onion, separating the whites, and place them in a pan.
Pour the sauce into the pan and warm it up, then add the fried chicken to the sauce.
