Preheat your oven to 400 degrees Fahrenheit and line a large baking sheet with parchment paper for easy cleanup.
Dice the chicken breast into one-inch cubes and chop the broccoli, bell pepper, and carrots into uniform, bite-sized pieces.
Spread the vegetables across the prepared baking sheet, drizzle with olive oil, season with sea salt and black pepper, and toss until evenly coated.
In a small mixing bowl, whisk together the coconut aminos, honey, minced ginger, minced garlic, and sesame oil to create the teriyaki glaze.
Add the chicken cubes to the baking sheet with the vegetables, pour half of the prepared glaze over the mixture, and stir to combine.
Roast in the center of the oven for 18 to 20 minutes until the chicken is cooked through and the vegetables are tender with slightly caramelized edges.
Remove from the oven, drizzle the remaining glaze over the hot chicken and vegetables, and garnish with sesame seeds before serving.
