Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced carrots with olive oil, half of the sea salt, and half of the black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 15-20 minutes until tender and slightly charred.
While vegetables roast, whisk together the coconut aminos, honey, grated ginger, minced garlic, and toasted sesame oil in a small bowl.
Season the chicken breast with the remaining salt and pepper. Heat a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and cooked through.
Reduce the skillet heat to low and pour the teriyaki sauce over the chicken, simmering for 1-2 minutes until the sauce thickens into a glossy glaze.
Slice the chicken and serve it over the roasted vegetables, drizzling any remaining sauce from the pan over the top.
Garnish with sesame seeds before serving.
