Heat a skillet over medium flame, and add sesame oil, ginger, and garlic. Saute for a minute and add soy sauce, brown sugar, cornstarch slurry, and salt. Bring it to a boil until the mixture starts to thicken and simmer for 3-4 minutes. Allow the teriyaki sauce to cool down.
To a bowl, add the chicken pieces and pour half of the prepared teriyaki sauce and marinate the chicken for at least 1 hour.
Thread a piece of chicken onto a wooden or metal skewer, followed by bell pepper and then a chicken piece and repeat until the end of the skewers.
Place the chicken skewers on the griddle or grill pan and cook for 8-10 minutes until the chicken is cooked through turning the skewers often.
Once done, brush the reserved teriyaki sauce over and garnish the chicken skewers with green onions and sesame seeds and serve.
