Dice the chicken breast into small, uniform bite-sized pieces and season thoroughly with sea salt, black pepper, garlic powder, and ground ginger.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat until shimmering.
Add the seasoned chicken to the pan and sear for 5-6 minutes, stirring occasionally, until golden brown and cooked through.
Push the chicken to one side of the pan and crack the egg into the empty space, scrambling it quickly until fully set.
Incorporate the cooked brown rice, frozen peas, and diced carrots into the pan, stirring to combine with the chicken and egg.
Drizzle the sesame oil and coconut aminos over the mixture, pressing the rice down firmly with a spatula for 2 minutes to create a slightly crispy texture.
Remove from heat and garnish with sliced green onions and toasted sesame seeds before serving hot.
