Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch cubes and chop the broccoli and red bell pepper into bite-sized pieces.
In a small mixing bowl, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic to create the teriyaki glaze.
Place the chicken cubes, broccoli, and peppers onto the prepared baking sheet.
Drizzle with olive oil and season with sea salt and black pepper, then toss thoroughly to coat.
Spread the mixture into a single layer, ensuring the chicken and vegetables aren't crowded so they roast rather than steam.
Roast in the oven for 18 to 20 minutes, tossing halfway through, until the chicken is cooked through and the vegetables have slightly charred edges.
Remove from the oven and immediately drizzle the teriyaki glaze over the hot chicken and vegetables, tossing to coat evenly.
Garnish with sesame seeds and serve warm.
