Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell peppers with 0.25 tablespoons of avocado oil, half the sea salt, and half the black pepper.
Spread the vegetables in a single layer on the baking sheet and roast for 15-18 minutes until tender and slightly charred.
While vegetables roast, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Season the chicken breast with the remaining sea salt and black pepper.
Heat the remaining 0.5 tablespoons of avocado oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes per side, or until the internal temperature reaches 165°F.
Reduce the heat to low and pour the teriyaki glaze into the skillet, tossing the chicken to coat thoroughly as the sauce thickens for 1-2 minutes.
Plate the chicken alongside the roasted vegetables and garnish with sesame seeds before serving.
