Cut your chicken into cubes and set aside. In a large bowl mix sesame oil, gluten free soy sauce, honey and rice wine vinegar until combined. Add the chicken to the soy and honey mix and stir until the chicken is coated.
Pour the chicken and sauce into a large (cold) saucepan and turn the heat to medium. Cook for around 10 minutes, until the chicken is cooked through and the sauce starts to thicken up. The sauce will become sticky, you will need to make sure you keep stirring as you cook so it doesn't burn.
Top with spring onion and sriracha mayo. Serve with rice and any stir fry vegetables of choice.
