Heat oil in a large skillet on medium high heat.

Add cubed chicken and brown chicken until cooked through and it is no longer pink.

While chicken is browning, prepare your teriyaki sauce by whisking together soy sauce, water, honey, brown sugar, rice vinegar, sesame oil, ginger, garlic, and cornstarch in a medium size mixing bowl.

Once chicken is browned and cooked through, add your homemade teriyaki sauce to your skillet and continue to cook stirring until the sauce has thickened.

Serve immediately with white or brown rice and vegetables of your choice. Garnish with sesame seeds and green onion.
