Slice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
In a small glass bowl, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic to create the teriyaki glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken pieces to the skillet in a single layer and sear until golden brown and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the skillet and set aside on a plate.
Add the broccoli florets, sliced bell peppers, and sugar snap peas to the same skillet, stir-frying for 3 to 4 minutes until they are tender-crisp.
Return the cooked chicken to the skillet and pour the teriyaki glaze over the meat and vegetables.
Toss everything together for 1 minute until the sauce thickens slightly and coats all ingredients.
Serve the stir-fry immediately over the warm cooked brown rice.
