Start by cooking the white rice according to package instructions. Set aside once done.
In a large skillet, heat the vegetable oil over medium-high heat. Add the chicken thighs and cook for about 5-7 minutes on each side, or until fully cooked and golden brown.
Remove the chicken from the skillet and let it rest for a few minutes before slicing it into bite-sized pieces.
In the same skillet, add the broccoli, bell peppers, and carrots. Stir-fry for about 3-4 minutes until the vegetables are tender-crisp.
In a small bowl, mix together the teriyaki sauce, soy sauce, honey, minced garlic, and minced ginger. Pour this sauce over the vegetables in the skillet and stir to combine.
Add the sliced chicken back into the skillet and toss everything together until well coated in the sauce. Cook for an additional 2-3 minutes to heat through.
To serve, place a scoop of cooked rice in a bowl and top with the teriyaki chicken and vegetable mixture. Sprinkle with sesame seeds and garnish with sliced green onions.
