Dice the chicken breast into small, uniform bite-sized pieces and season them evenly with the sea salt, black pepper, garlic powder, and ground ginger.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat until it begins to shimmer.
Add the seasoned chicken to the skillet and cook, stirring occasionally, until the pieces are golden brown and cooked through, approximately 5 to 7 minutes.
Push the cooked chicken to one side of the pan and crack the egg into the empty space, scrambling it quickly with a spatula until fully set.
Add the diced carrots and frozen peas to the pan, sautéing for 2 minutes until the carrots begin to soften.
Stir in the cooked brown rice and coconut aminos, tossing all ingredients together for another 3 minutes until the rice is heated through and slightly crisp.
Thinly slice the green onions and fold them into the rice just before removing from the heat.
Transfer the fried rice to a bowl and serve immediately while hot.
