In a large bowl, combine chicken breasts and soy sauce and let it marinate for 30 minutes.
Drain the chicken and keep it aside.
In another bowl, add the marinated chicken, egg whites, cornstarch and mix well. Make sure the egg whites and the cornstarch mixture fully coat the chicken pieces.
Now, in a wok, heat oil and fry the chicken pieces until golden brown and set aside.
Drain the oil from the work and add chopped garlic, soy sauce, honey, lime juice, ketchup and mix them together.
Add salt and pepper according to taste and stir until everything is combined well together.
Tip in the chicken pieces and mix, making sure all the pieces are coated in the sauce.
Remove from heat, plate and garnish with chopped green onions.
