Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets, sliced carrots, and bell peppers with half of the avocado oil, sea salt, and black pepper on the prepared baking sheet.
Roast the vegetables for 15-20 minutes until they are tender and show slight caramelized edges.
While the vegetables roast, season the chicken breast with a pinch of salt and pepper.
Heat the remaining avocado oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until cooked through.
In a small bowl, whisk together the coconut aminos, honey, ground ginger, and garlic powder to create the teriyaki glaze.
Reduce the skillet heat to low, pour the glaze over the chicken, and let it simmer for 2 minutes until it thickens into a sticky coating.
Slice the chicken and serve it over the roasted vegetables, garnishing with sesame seeds for added texture.
