Preheat oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets, sliced bell peppers, and carrots with half of the avocado oil, sea salt, and black pepper.
Roast the vegetables for 18 to 20 minutes until they are tender and show slight charred edges.
While vegetables roast, slice the chicken breast into bite-sized pieces and toss in a bowl with arrowroot powder until lightly coated.
Heat the remaining avocado oil in a large skillet over medium-high heat and sear the chicken until golden brown and crispy on all sides.
In a small jar, whisk together the coconut aminos, honey, minced ginger, and minced garlic.
Reduce the skillet heat to medium-low and pour the sauce over the chicken, stirring constantly until the glaze thickens and coats the meat beautifully.
Divide the roasted vegetables onto a plate, top with the crispy teriyaki chicken, and garnish with sesame seeds before serving.
