Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into uniform 1-inch cubes and chop the broccoli, bell pepper, and carrots into bite-sized pieces.
In a small mixing bowl, whisk together the coconut aminos, honey, sesame oil, freshly grated ginger, and minced garlic to create the teriyaki glaze.
Spread the chicken and vegetables across the prepared baking sheet in a single layer and season with sea salt and black pepper.
Drizzle half of the prepared glaze over the chicken and vegetables, tossing thoroughly to ensure every piece is well coated.
Roast in the oven for 18-20 minutes, or until the chicken is cooked through and the vegetables are tender with slightly charred edges.
Remove from the oven, drizzle with the remaining glaze for extra flavor, and garnish with sesame seeds before serving hot.
