Slice the chicken breast into thin, bite-sized strips 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 stir-fry sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken strips to the skillet and sear until golden brown and cooked through, about 5-6 minutes.
Remove the chicken from the skillet and set aside, then add the broccoli florets, sliced red bell pepper, and sugar snap peas.
Sauté the vegetables for 3-4 minutes until they are tender-crisp and vibrant in color.
Return the chicken to the skillet and pour the sesame-ginger sauce over the mixture, tossing well to coat everything evenly.
Serve the hot chicken and vegetable mixture over the cooked brown rice.
