Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the red bell pepper into strips and the carrot into thin rounds.
Place the broccoli, bell pepper, and carrots on the baking sheet, tossing them with the olive oil, sea salt, and black pepper.
Roast the vegetables for 18 to 20 minutes until they are tender and slightly charred at the edges.
While the vegetables roast, season the chicken breast with a small pinch of salt and sear it in a skillet over medium-high heat with the toasted sesame oil for 5-6 minutes per side.
In a small bowl, whisk together the tamari, honey, minced ginger, and minced garlic to create the teriyaki glaze.
Lower the skillet heat to medium-low, pour the sauce over the chicken, and let it simmer for 2 minutes until the glaze is thick and glossy.
Slice the chicken and serve it over the roasted vegetable medley, finishing with a sprinkle of sesame seeds.
