Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Slice the red bell pepper into thin strips and toss them on the baking sheet with the broccoli florets and sugar snap peas.
Drizzle the vegetables with half of the olive oil, sea salt, and black pepper, then roast for 15-18 minutes until tender-crisp and slightly charred.
While the vegetables roast, whisk together the tamari, honey, minced fresh ginger, and minced garlic in a small bowl to create the teriyaki glaze.
Heat the remaining olive oil in a medium skillet over medium-high heat and sear the chicken breast for 6-7 minutes per side until the internal temperature reaches 165°F.
Reduce the skillet heat to low and pour the teriyaki glaze over the chicken, turning the meat to coat it thoroughly as the sauce bubbles and thickens into a sticky glaze.
Slice the chicken into strips and serve immediately over the roasted vegetables, garnished with a sprinkle of sesame seeds.
