Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper.
Cut the chicken breast into 1-inch bite-sized cubes and slice the red bell pepper into thin strips.
Place the chicken cubes, broccoli florets, and bell pepper strips in a large bowl.
In a small mixing bowl, whisk together the honey, tamari, minced garlic, and grated ginger until well combined.
Drizzle the olive oil over the chicken and vegetables, then season with sea salt and black pepper, tossing to coat everything evenly.
Spread the chicken and vegetables out in a single layer on the prepared sheet pan.
Roast in the oven for 15-18 minutes, or until the chicken is cooked through and the vegetables are tender.
Remove the pan from the oven, pour the honey-garlic glaze over the ingredients, and toss with a spatula to coat.
Return the pan to the oven for an additional 2-3 minutes until the glaze is bubbly and slightly thickened.
Garnish with sesame seeds and serve immediately.
