Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced carrots, and sliced bell peppers on the baking sheet, tossing them with 0.5 tablespoons of olive oil, sea salt, and black pepper.
Roast the vegetables for 15-20 minutes until they are tender and show light golden-brown edges.
While the vegetables roast, whisk together the coconut aminos, honey, toasted sesame oil, grated ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast lightly with a pinch of salt and pepper.
Heat the remaining 0.5 tablespoons of olive oil in a non-stick skillet over medium-high heat.
Sear the chicken for 5-7 minutes per side until the internal temperature reaches 165°F and the exterior is golden.
Lower the heat to medium-low and pour the teriyaki glaze into the skillet, tossing the chicken constantly for 1-2 minutes until the sauce reduces into a thick, glossy coating.
Slice the chicken into strips and serve immediately over the roasted vegetables, finishing with a sprinkle of sesame seeds.
