Dice the chicken into small, uniform pieces and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the seasoned chicken to the pan and sear until golden brown and fully cooked, then remove and set aside.
In the same pan, add the diced carrots and frozen peas, sautéing for 3-4 minutes until the carrots are slightly tender.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until the mixture becomes fragrant.
Push the vegetables to one side of the pan, crack the egg into the empty space, and scramble until just set.
Add the cooked brown rice and the prepared chicken back into the skillet, tossing everything together to combine.
Drizzle the tamari and toasted sesame oil over the mixture, stirring constantly for 1-2 minutes to incorporate the flavors.
Garnish the dish with thinly sliced green onions and serve while hot.
