Preheat your oven to 400°F and line a large rimmed sheet pan with parchment paper for easy cleanup.
Dice 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 raw honey, tamari, minced garlic, and toasted sesame oil until well combined.
Place the chicken, broccoli, and peppers onto the prepared sheet pan.
Drizzle the olive oil over the chicken and vegetables, then season with sea salt and black pepper.
Pour the honey-garlic sauce over the mixture and toss thoroughly with tongs to ensure every piece is coated.
Spread the ingredients into a single, even layer to ensure even roasting and caramelization.
Bake for 18 to 20 minutes, or until the chicken is cooked through and the vegetables are tender-crisp.
Remove from the oven and garnish with sesame seeds before serving.
