Slice the chicken breast into bite-sized pieces and season with the sea salt and black pepper.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook until golden and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the pan and set aside; add the broccoli, bell peppers, and snap peas to the same skillet.
Stir-fry the vegetables for 3 to 4 minutes until they are tender-crisp and bright in color.
In a small bowl, whisk together the tamari, grated fresh ginger, minced garlic, and honey.
Return the chicken to the skillet, pour the sauce over the mixture, and toss for 1 minute to coat everything evenly.
Serve the hot stir-fry immediately over the warm cooked brown rice.
