Dice the chicken breast into small, uniform pieces and season with sea salt and black pepper.
Heat the sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and sauté until golden brown and cooked through, then remove and set aside.
In the same pan, add the finely diced carrots, minced garlic, and grated ginger, sautéing for 2 minutes until fragrant.
Push the vegetables to the side of the pan, crack the egg into the center, and scramble until just set.
Add the cooked brown rice, frozen peas, and the cooked chicken back into the skillet.
Pour the coconut aminos over the mixture and toss everything together for 3 minutes until the rice is slightly crispy and well-combined.
Garnish with thinly sliced green onions and serve immediately.
