Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell pepper with 0.5 tbsp of avocado oil, sea salt, and black pepper.
Spread the vegetables in a single layer and roast for 15-18 minutes until they are crisp-tender and slightly charred.
While the vegetables roast, mince the garlic and grate the fresh ginger.
In a small bowl, whisk together the tamari, honey, sesame oil, minced ginger, and garlic to create the teriyaki glaze.
Cut the chicken breast into bite-sized pieces and season lightly with a pinch of salt.
Heat the remaining 0.5 tbsp of avocado oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6-8 minutes, turning occasionally, until golden brown and fully cooked.
Lower the heat to medium and pour the sauce over the chicken, stirring constantly for 1-2 minutes until the glaze is thick and glossy.
Plate the glazed chicken alongside the roasted vegetables and serve immediately.
