Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with the avocado oil and half of the sea salt and black pepper on the prepared baking sheet.
Roast the vegetables for 15-20 minutes until they are tender and show slight charred edges.
While the vegetables roast, whisk together the coconut aminos, honey, toasted sesame oil, garlic powder, and ginger powder in a small bowl to create the teriyaki sauce.
Season the chicken breast with the remaining sea salt and black pepper.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until cooked through.
Lower the heat and pour the teriyaki sauce into the skillet, tossing the chicken continuously for 1-2 minutes until the glaze is thick and glossy.
Slice the chicken and serve it over the roasted vegetables, garnishing with sesame seeds for added texture.
