In a small bowl, mix soy sauce, garlic, ginger, honey, sesame seeds, green onions, and optional sriracha.
Add cubed chicken to a bowl and pour in two-thirds of the sauce. Let marinate while prepping veggies.
Heat a large skillet over medium-high heat. Cook the chicken for about 8 minutes, until golden and fully cooked. Remove and set aside.
In the same pan, add the sliced bell peppers, onion, peas, and remaining sauce. Stir fry for about 11 minutes, or until vegetables are tender.
Return the chicken to the skillet and stir everything together. Simmer 1–2 minutes to thicken the sauce.
Serve hot over rice or noodles, garnished with sesame seeds and green onions.
