Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into one-inch cubes and chop the bell pepper, carrots, and broccoli into bite-sized pieces.
In a small bowl, whisk together the coconut aminos, honey, sesame oil, minced ginger, and minced garlic to create the clean teriyaki glaze.
Spread the chicken and vegetables across the baking sheet, drizzle with avocado oil, and season with sea salt and black pepper.
Roast in the oven for 15 to 18 minutes, or until the chicken is cooked through and the vegetables are tender-crisp.
Remove the sheet from the oven, pour the teriyaki glaze over the chicken and vegetables, and toss thoroughly to coat.
Return the pan to the oven for an additional 2 minutes to allow the sauce to thicken and stick to the ingredients.
Garnish with sesame seeds and serve immediately while hot.
