Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the broccoli florets and sliced red bell pepper on the sheet, drizzle with olive oil, and roast for 15-18 minutes until tender and slightly charred.
While vegetables roast, cut the chicken breast into 1-inch cubes and place them in a bowl.
Toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar or bowl, whisk together the coconut aminos, raw honey, minced fresh ginger, and minced garlic to create the glaze.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken cubes to the skillet in a single layer and sear for 3-4 minutes per side until golden brown and crispy.
Reduce the heat to medium and pour the teriyaki glaze over the chicken, stirring constantly for 1-2 minutes until the sauce thickens and coats the meat.
Plate the roasted vegetables and top with the crispy teriyaki chicken.
Garnish with sesame seeds before serving.
