Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Place the broccoli florets, sliced bell peppers, and snap peas on the baking sheet. Drizzle with avocado oil and season with sea salt and black pepper, tossing to coat evenly.
Roast the vegetables for 15-18 minutes until they are tender and show light golden-brown edges.
While the vegetables roast, whisk together the coconut aminos, honey, grated ginger, minced garlic, and toasted sesame oil in a small bowl to create the teriyaki glaze.
Season the chicken breast with a small pinch of salt and sear in a hot non-stick skillet over medium-high heat for 6-7 minutes per side until fully cooked and golden.
Reduce the skillet heat to low and pour the teriyaki glaze over the chicken. Simmer for 1-2 minutes, flipping the chicken to ensure it is thoroughly coated in the thickened, glossy sauce.
Arrange the roasted vegetables on a plate, top with the glazed chicken, and garnish with sesame seeds before serving.
