Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with 1 tsp of avocado oil, sea salt, and black pepper on the prepared sheet.
Roast the vegetables for 15-18 minutes until the broccoli edges are slightly charred and the peppers are tender.
While the vegetables roast, whisk together the coconut aminos, honey, toasted sesame oil, minced fresh ginger, and minced garlic in a small bowl.
Dice the chicken breast into 1-inch cubes and season lightly with an extra pinch of salt.
Heat the remaining 1 tsp of avocado oil in a large non-stick skillet over medium-high heat and sear the chicken until golden brown and cooked through.
Reduce the skillet heat to low, pour the teriyaki sauce over the chicken, and toss for 1-2 minutes until the glaze is thick and glossy.
Serve the crispy chicken over the roasted vegetables and garnish with sesame seeds.
