Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the carrots into rounds and the red bell pepper into thin strips.
Toss the broccoli, carrots, and peppers on the baking sheet with half of the avocado oil, sea salt, and black pepper.
Roast the vegetables for 15-20 minutes until they are tender and show slightly caramelized edges.
While the vegetables roast, dice the chicken breast into 1-inch bite-sized cubes.
Season the chicken cubes evenly with garlic powder and ground ginger.
Heat the remaining avocado oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes, turning occasionally until golden brown and cooked through.
Reduce the heat to low and pour in the coconut aminos and sesame oil.
Stir the chicken constantly for 1-2 minutes until the sauce reduces into a thick, glossy glaze that coats the meat.
Remove the roasted vegetables from the oven and divide them onto plates.
Top the vegetables with the glazed chicken and garnish with sesame seeds before serving.
