Cut the chicken breast into bite-sized pieces, pat dry with paper towels, and season with sea salt and black pepper.
In a small bowl, whisk together the honey, tamari, minced garlic, and grated fresh ginger to create the sauce.
Heat the olive oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and cook until golden-brown and cooked through, approximately 6 to 8 minutes.
Remove the chicken from the skillet and set aside on a plate.
Add the broccoli florets and sliced red bell pepper to the same skillet, sautéing for 3 to 4 minutes until tender-crisp.
Return the chicken to the skillet and pour the honey-garlic sauce over the chicken and vegetables.
Toss everything together for 1 to 2 minutes until the sauce thickens and creates a glossy glaze.
Garnish with sesame seeds and serve immediately.
