Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Slice the red bell pepper and carrots into bite-sized pieces, then toss them on the baking sheet with the broccoli florets, half of the avocado oil, and a pinch of sea salt.
Roast the vegetables for 15-18 minutes, tossing halfway through, until they are tender and show slight charred edges.
While the vegetables roast, season the chicken breast with sea salt and black pepper.
Heat the remaining avocado oil in a medium skillet over medium-high heat. Sear the chicken for 5-6 minutes per side until golden brown and cooked through.
In a small bowl, whisk together the coconut aminos, honey, grated fresh ginger, minced garlic, and toasted sesame oil.
Reduce the skillet heat to low, pour the sauce over the chicken, and simmer for 2-3 minutes until the glaze is thick and glossy.
Slice the chicken and serve it alongside the roasted vegetables, drizzling any remaining pan sauce over the top and garnishing with sesame seeds.
