Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli, carrots, and bell peppers on the baking sheet with half of the avocado oil, half of the sea salt, and half of the black pepper.
Roast the vegetables for 15-20 minutes until they are tender and show slight charred edges.
While vegetables roast, whisk together the coconut aminos, raw honey, grated ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast with the remaining salt and pepper. Heat the remaining oil in a 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, pour the teriyaki glaze over the chicken, and simmer for 2 minutes, flipping the chicken until the sauce becomes thick and glossy.
Slice the chicken and serve it over the roasted vegetables, drizzling any remaining glaze from the pan over the top.
Garnish with sesame seeds before serving.
