Slice the chicken breast into bite-sized pieces and season with 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 pan and sear until golden brown and cooked through, approximately 5-7 minutes.
Remove the chicken from the pan and set it aside on a plate.
In the same pan, 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 bright in color.
Stir in the minced garlic and grated fresh ginger, cooking for about 30 seconds until fragrant.
Return the cooked chicken to the pan and pour in the coconut aminos.
Toss everything together for 1 minute to ensure the chicken and vegetables are well-coated in the glaze.
Serve the stir-fry over the warm, cooked brown rice and garnish with sesame seeds and sliced green onions.
