Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with half of the avocado oil, sea salt, and black pepper on the baking sheet.
Roast the vegetables for 15-18 minutes until they are tender and slightly charred at the edges.
While the vegetables roast, whisk together the coconut aminos, honey, toasted sesame oil, minced ginger, and minced garlic in a small bowl.
Season the chicken breast with a pinch of salt and sear in a hot skillet with the remaining avocado oil for 5-6 minutes per side until golden brown and cooked through.
Lower the heat to medium-low, pour the teriyaki sauce mixture over the chicken, and simmer for 2-3 minutes until the glaze is thick and glossy.
Slice the chicken into strips and serve immediately over the roasted vegetables, garnishing with sesame seeds.
