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, grated 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.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5-6 minutes, then remove from the pan and set aside.
In the same skillet, add the broccoli florets, sliced red bell pepper, and snap peas, stir-frying for 3-4 minutes until the vegetables are tender-crisp.
Return the chicken to the skillet and pour the ginger-garlic sauce over the mixture, tossing everything together for 1 minute until the sauce thickens slightly.
Serve the hot stir-fry immediately over the cooked brown rice.
