Dice the chicken breast into small, even pieces and season lightly with sea salt and black pepper.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through.
Stir in the diced carrots and frozen peas, cooking for another 3 minutes until the carrots are slightly tender.
Add the minced garlic and grated fresh ginger, sautéing for about 60 seconds until fragrant.
Push the chicken and vegetable mixture to the outer edges of the skillet to create an opening in the center.
Crack the egg into the center of the pan and scramble it until just set, then incorporate it into the rest of the mixture.
Add the cooked brown rice, coconut aminos, and toasted sesame oil to the skillet.
Toss all ingredients together for 2-3 minutes, allowing the rice to heat through and absorb the savory flavors.
Season with the remaining sea salt and black pepper, then garnish with thinly sliced green onions before serving warm.
