Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced bell peppers, and sliced carrots on the baking sheet, tossing them with the olive oil, sea salt, and black pepper.
Roast the vegetables for 18-20 minutes until they are tender and slightly charred at the edges.
While the vegetables roast, whisk together the coconut aminos, honey, sesame oil, grated ginger, and minced garlic in a small bowl to create the teriyaki sauce.
Heat a large non-stick skillet over medium-high heat and sear the diced chicken breast pieces until they are golden brown and fully cooked through.
Reduce the heat to low, pour the teriyaki sauce into the skillet with the chicken, and stir constantly for 2 minutes until the glaze is thick and glossy.
Plate the roasted vegetables and top with the glazed chicken, finishing the dish with a sprinkle of sesame seeds.
