Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Dice the chicken breast into 1-inch bite-sized pieces and chop the broccoli, bell pepper, and carrots into uniform sizes.
In a small mixing bowl, whisk together the coconut aminos, honey, sesame oil, grated fresh ginger, and minced garlic to create the teriyaki glaze.
Place the diced chicken and chopped vegetables onto the prepared baking sheet.
Season the chicken and vegetables with sea salt and black pepper, then drizzle with half of the prepared glaze.
Toss everything together on the pan until evenly coated and spread the mixture into a single layer.
Roast in the oven for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender-crisp.
Remove from the oven, drizzle with the remaining glaze, and garnish with sesame seeds before serving.
