Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
Heat the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the chicken to the pan and sauté until golden brown and cooked through, approximately 5-6 minutes, then remove and set aside.
In the same skillet, add the diced onion, minced garlic, and grated ginger, sautéing until the onion is translucent and fragrant.
Stir in the frozen peas and carrots and cook for 2-3 minutes until tender.
Push the vegetable mixture to one side of the pan and crack the egg into the empty space, scrambling it until fully set.
Add the cooked brown rice and the prepared chicken back into the pan.
Drizzle the coconut aminos over the mixture and toss everything together for 2 minutes until the rice is slightly toasted and well-combined.
