Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets and sliced red bell peppers with half of the avocado oil, sea salt, and black pepper.
Spread the vegetables in a single layer and roast for 15-20 minutes until the edges are caramelized and tender.
While vegetables roast, whisk together the tamari, honey, sesame oil, grated fresh ginger, and minced garlic in a small bowl.
Slice the chicken breast into bite-sized pieces and season lightly with salt.
Heat the remaining avocado oil in a large skillet over medium-high heat and sear the chicken until golden and cooked through.
Reduce the heat to low, pour the tamari mixture over the chicken, and toss for 1-2 minutes until the sauce becomes a thick, glossy glaze.
Plate the roasted vegetables and top with the glazed chicken, drizzling any remaining sauce from the pan over the top.
