Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced red bell pepper, and zucchini on the sheet and toss with olive oil, sea salt, and black pepper.
Roast the vegetables for 15 to 18 minutes until tender and slightly charred at the edges.
While vegetables roast, pat the chicken breast dry, cut into 1-inch cubes, and toss in a bowl with arrowroot powder until lightly coated.
In a small jar, whisk together the coconut aminos, honey, minced ginger, and minced garlic to create the teriyaki base.
Heat the sesame oil in a large non-stick skillet over medium-high heat, then add chicken and sear for 5-6 minutes until golden and crispy.
Reduce heat to medium, pour the sauce over the chicken, and stir constantly for 1-2 minutes until the glaze is thick and glossy.
Plate the roasted vegetables and top with the crispy teriyaki chicken, finishing with a sprinkle of sesame seeds.
