In a large bowl, mix all the marinade ingredients together.
Slice the chicken into strips (½" x 2"). I use kitchen shears to cut the slices.
Add the chicken strips to the marinade and refrigerate for a minimum of 2 hours ( I aim for 6-8 hours).
Heat some vegetable oil in a frying pan or cast iron skillet.
Cook the chicken in batches on medium heat, ensuring not to overcrowd the the pieces so they caramelize slightly. Cook for approximately 8-10 minutes or until the chicken is cooked through. Toss a few times while sautéing.
Serve immediately over jasmine rice and garnish with scallions and sesame seeds if desired.
