Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and cook until golden brown and cooked through, then remove and set aside.
In the same pan, add sesame oil, minced garlic, and grated fresh ginger, sautéing until fragrant.
Add the diced carrots and frozen peas to the pan, stir-frying for 3-4 minutes until the carrots are tender.
Push the vegetables to the side of the pan, crack the egg into the center, and scramble until just set.
Add the cooked brown rice and the cooked chicken back into the pan, drizzling the coconut aminos over the top.
Stir everything together over high heat for 2 minutes to combine flavors, then garnish with sliced green onions before serving.
