Dice the chicken breast into bite-sized half-inch pieces and season with sea salt and black pepper.
Finely dice the carrots, mince the garlic, and grate the fresh ginger.
Heat a large non-stick skillet or wok over medium-high heat and add the toasted sesame oil.
Add the chicken to the pan and sauté for 5-6 minutes until golden brown and cooked through, then remove and set aside.
In the same pan, add the carrots and peas, sautéing for 3-4 minutes until the carrots are tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 30 seconds until fragrant.
Push the vegetables 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 cooked chicken back into the pan, stirring everything together.
Drizzle the tamari over the mixture and toss well to coat, allowing the rice to heat through for 2 minutes.
Garnish with sliced green onions and serve immediately.
