Preheat your oven to 425°F and prepare a large sheet pan.
Cut the bell pepper into bite-sized 1-inch pieces. Thinly slice the green onion and set aside for garnish. Cut the chicken into thin strips so it cooks evenly.
In a large mixing bowl, whisk together the soy sauce, olive oil, honey, and seasonings until well combined.
Add the chicken, peas, carrots, and bell pepper. Toss until everything is evenly coated in the sauce.
Transfer the mixture to the sheet pan and spread it out into an even layer. Pour any remaining sauce from the bowl over the top.
Bake for 20 to 25 minutes, or until the chicken is fully cooked and the vegetables are tender.
Remove the pan from the oven and sprinkle with the sliced green onions and sesame seeds.
Serve as is, or spoon it over cooked rice or noodles for a more filling meal.
