Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the broccoli florets, sliced red bell pepper, and sliced carrots with olive oil, sea salt, and black pepper on the prepared baking sheet.
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, sesame oil, minced ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast with a tiny pinch of salt and sear in a hot skillet over medium-high heat for 5-6 minutes per side until fully cooked.
Pour the teriyaki sauce into the skillet during the last 2 minutes of cooking, tossing the chicken continuously until the sauce reduces into a thick, glossy glaze.
Slice the chicken into strips and serve immediately over the roasted vegetables, garnishing with sesame seeds for a final crunch.
