Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Season the diced chicken breast with sea salt and black pepper, then add to the skillet.
Sear the chicken until golden brown and cooked through, approximately 5-6 minutes, then remove from the pan and set aside.
In the same skillet, add the carrots and broccoli, sautéing for 3-4 minutes until they are tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 30 seconds until highly fragrant.
Push the vegetables to the outer edges of the pan and crack the egg into the center, scrambling until fully set.
Add the cooked brown rice, frozen peas, and the cooked chicken back into the skillet.
Drizzle with tamari and sesame oil, tossing everything together over high heat for 2 minutes to crisp the rice.
Garnish with thinly sliced green onions and serve immediately.
