Dice the chicken breast into small, uniform bite-sized pieces and season with sea salt and black pepper.
Heat a large non-stick skillet or wok over medium-high heat and lightly coat with a small amount of avocado oil spray if needed.
Whisk the egg in a small bowl, pour into the hot skillet, scramble quickly until just set, then remove and set aside.
In the same skillet, add the chicken pieces and sauté until golden brown and cooked through, approximately 5-6 minutes.
Add the diced carrots, frozen peas, minced garlic, and grated ginger to the skillet with the chicken, stirring frequently for 2-3 minutes until the vegetables are tender-crisp.
Incorporate the cooked brown rice and toasted sesame oil, pressing the rice down to ensure it gets slightly crispy and heated through.
Pour the coconut aminos over the mixture and toss everything together until the rice is evenly coated and steaming.
Fold the scrambled egg back into the rice and garnish with thinly sliced green onions before serving.
