Preheat your oven to 400°F (200°C).
On a large baking sheet, toss the broccoli florets, sliced red bell pepper, and carrots with the avocado oil, sea salt, and black pepper.
Roast the vegetables for 15-20 minutes until they are tender and show slight charred edges.
While the vegetables roast, whisk together the tamari, honey, grated fresh ginger, and minced garlic in a small bowl.
Heat the sesame oil in a large skillet over medium-high heat.
Add the chicken breast pieces to the skillet and cook for 5-7 minutes, turning occasionally until golden brown and cooked through.
Pour the prepared teriyaki sauce into the skillet with the chicken and simmer for 2 minutes until the sauce reduces into a thick, glossy glaze.
Arrange the roasted vegetables on a plate, top with the glazed chicken, and garnish with sesame seeds before serving.
