Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced bell peppers, and sliced carrots on the baking sheet. Drizzle with avocado oil, sea salt, and black pepper, then toss to coat evenly.
Roast the vegetables in the oven for 15-18 minutes until they are tender and show slight charred edges.
While the vegetables roast, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast with a pinch of salt and pepper. Heat the toasted sesame oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes per side until golden brown and cooked through.
Reduce the heat to low and pour the teriyaki sauce over the chicken, tossing frequently for 1-2 minutes until the sauce thickens into a glossy glaze.
Slice the chicken and serve it over the roasted vegetables, garnishing the entire dish with sesame seeds.
