Dice the chicken breast into small, uniform bite-sized pieces and mince the garlic and ginger.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan, seasoning with sea salt and black pepper, and sauté until golden brown and cooked through.
Push the chicken to one side of the pan, crack the egg into the empty space, and scramble quickly until just set.
Stir in the diced carrots, frozen peas, minced garlic, and grated ginger, cooking for 2 minutes until the vegetables are tender-crisp.
Add the cooked brown rice and coconut aminos to the skillet, tossing vigorously to combine and break up any rice clumps.
Cook for another 2-3 minutes until the rice is heated through and slightly toasted.
Remove from heat, drizzle with toasted sesame oil, and garnish with thinly sliced green onions before serving.
