In a large bowl, combine diced chicken with 2 tablespoons of teriyaki sauce, grated ginger, and minced garlic. Marinate for at least 20 minutes.
In a large skillet or wok, heat the sesame oil over medium-high heat. Add the marinated chicken and cook for 5-7 minutes, until the chicken is cooked through and lightly browned.
Add the broccoli, red bell pepper, and snap peas to the skillet, stirring frequently. Cook for an additional 3-5 minutes, or until the vegetables are tender-crisp.
Pour in the remaining teriyaki sauce and stir to evenly coat the chicken and vegetables. Cook for another minute to heat through.
To assemble the bowls, place a generous scoop of cooked jasmine rice in each bowl, topped with the teriyaki chicken and vegetable stir-fry.
Garnish each bowl with chopped green onions and a sprinkle of sesame seeds.
