Prepare the brown rice according to package directions and set aside.
Dice the chicken breast into 1-inch pieces and season with sea salt and black pepper.
In a small bowl, whisk together the tamari, honey, minced fresh ginger, and minced garlic to create the teriyaki sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté 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, sliced red bell pepper, and sugar snap peas to the same skillet with a tablespoon of water.
Cover and steam-sauté the vegetables for 3 minutes until they are vibrant and tender-crisp.
Return the chicken to the skillet and pour the teriyaki sauce over the chicken and vegetables.
Toss everything together for 1 to 2 minutes until the sauce has thickened and evenly coated the ingredients.
Serve the teriyaki chicken and vegetables over the warm brown rice and garnish with sesame seeds.
