Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
In a small bowl, whisk the egg until smooth.
Heat a large skillet or wok over medium-high heat and add half of the sesame oil.
Pour the egg into the skillet, scramble quickly until just set, then remove and set aside.
Add the remaining sesame oil to the skillet and sear the chicken pieces until golden brown and cooked through, about 5-6 minutes.
Add the diced carrots, minced ginger, and minced garlic to the skillet, sautéing for 2-3 minutes until the carrots begin to soften.
Stir in the cooked brown rice and frozen peas, breaking up any clumps of rice and tossing frequently for 2 minutes.
Drizzle the coconut aminos over the mixture and fold in the cooked egg and sliced green onions.
Toss everything together for one final minute until the rice is slightly toasted and everything is well combined.
Serve immediately in a bowl, garnished with extra green onions if desired.
