To make the marinade, mix together the soy sauce, sesame oil, minced garlic, and pepper flakes in a small bowl. Place the chicken strips together with the marinade in a zip lock bag and toss to coat. Leave in a fridge for at least an hour.
Combine all the sauce ingredients in a bowl and whisk until smooth.
