Teriyaki Chicken Stir-Fry

Whisk teriyaki marinade, soy sauce, ginger, brown sugar, red pepper flakes, and black pepper together in a large glass or ceramic bowl.

Add chicken and toss to evenly coat.

Cover the bowl with plastic wrap and marinate in the refrigerator for 5 hours.

Heat a wok over medium-high heat.

Add scallions, garlic, and oil; stir-fry for about 1 minute.

Add broccoli, snow peas, and bell pepper; stir-fry for 2 minutes more.

Add stir-fry sauce and mix until vegetables are coated.

Remove chicken from the marinade and shake off excess.

Discard the remaining marinade.

Add chicken to the wok and stir-fry until chicken is no longer pink in the center and the juices run clear, about 5 minutes.
