Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Place the broccoli florets and sliced red bell pepper on the baking sheet, drizzle with olive oil, and season with half of the salt and pepper.
Roast the vegetables for 15-18 minutes until they are tender and show slight charring at the edges.
While the vegetables roast, whisk together the coconut aminos, honey, grated ginger, and minced garlic in a small bowl to create the teriyaki base.
Cut the chicken breast into bite-sized pieces, season with the remaining salt and pepper, and sear in a hot non-stick skillet until golden and cooked through.
Reduce the skillet heat to medium-low and pour in the teriyaki sauce, stirring constantly for 1-2 minutes until the sauce thickens into a glossy glaze that coats the chicken.
Remove the roasted vegetables from the oven and toss them directly into the skillet with the glazed chicken.
Plate the meal immediately and garnish with sesame seeds and thinly sliced green onions for a fresh finish.
