Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Dice the chicken breast into bite-sized pieces and season with sea salt, black pepper, garlic powder, and ground ginger.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5-6 minutes.
Push the cooked chicken to the outer edges of the pan and crack the egg into the center, scrambling it quickly until fully set.
Incorporate the frozen peas, frozen carrots, and chilled brown rice into the skillet, using a spatula to break up any rice clumps.
Drizzle the coconut aminos and toasted sesame oil over the mixture, tossing everything together for 3-4 minutes until the rice is heated and slightly crispy.
Remove from heat, stir in the sliced green onions, and serve immediately.
