Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets, sliced red bell peppers, and sliced carrots with olive oil, sea salt, and black pepper on the prepared 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, grated fresh ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Season the chicken breast with a tiny pinch of salt and sear in the skillet for 5-7 minutes per side until golden brown and cooked through.
Pour the teriyaki sauce into the skillet during the final 2 minutes of cooking, tossing the chicken continuously until the glaze is thick and glossy.
Slice the chicken and serve it immediately over the roasted vegetables, garnished with sesame seeds for a crunch.
