Slice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, minced garlic, and grated fresh ginger to create the stir-fry sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through, then remove the chicken and set it aside on a plate.
Add the sesame oil to the same skillet, then toss in the broccoli florets, sliced red bell pepper, and sugar snap peas.
Stir-fry the vegetables for 3-4 minutes until they are tender-crisp and vibrant in color.
Return the cooked chicken to the skillet and pour the prepared ginger-sauce over the meat and vegetables.
Toss everything together for 1-2 minutes until the sauce has thickened slightly and coats every piece.
Serve the hot stir-fry over the warm cooked brown rice and garnish with a sprinkle of sesame seeds.
