Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Place the broccoli florets, sliced red bell pepper, and snap peas on the sheet, tossing them with olive oil, sea salt, and black pepper.
Roast the vegetables for 15 to 18 minutes until they are tender and show slight charred edges.
In a small bowl, whisk together the tamari, honey, sesame oil, minced ginger, and minced garlic to create the glaze.
Heat a non-stick skillet over medium-high heat and sear the chicken breast for 5 to 6 minutes per side until golden and cooked through.
Lower the heat, pour the sauce over the chicken, and simmer for 2 minutes until the glaze is thick and glossy.
Slice the chicken and serve it over the roasted vegetable medley, finishing with a sprinkle of sesame seeds.
