Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Arrange the broccoli florets and sliced bell peppers on the sheet, drizzle with olive oil, and toss with sea salt and black pepper.
Roast the vegetables for 18-20 minutes until they are tender and have developed slightly charred, caramelized edges.
While the vegetables roast, whisk together the coconut aminos, honey, sesame oil, minced ginger, and minced garlic in a small bowl.
Season the chicken breast with a pinch of salt and pepper, then sear in a non-stick skillet over medium-high heat for 5-6 minutes per side.
Reduce the heat to medium, pour the teriyaki glaze into the skillet, and simmer for 2-3 minutes until the sauce thickens and coats the chicken.
Slice the chicken into strips and serve over the roasted vegetable medley, finishing with a sprinkle of toasted sesame seeds.
