Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced red bell pepper, and carrots on the baking sheet, then toss with olive 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 coconut aminos, toasted sesame oil, honey, minced fresh ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast with a small pinch of salt and sear in a non-stick pan over medium-high heat for 5-6 minutes per side until fully cooked.
Reduce the pan heat to low and pour the teriyaki glaze over the chicken, simmering for 1-2 minutes until the sauce thickens into a glossy coating.
Slice the chicken and serve it immediately over the roasted vegetables, garnishing with sesame seeds for a final crunch.
