Dice the chicken breast into small, even bite-sized pieces and season with the sea salt and black pepper.
Heat a large skillet or wok over medium-high heat and add half of the toasted sesame oil.
Add the chicken to the skillet and cook for 5-6 minutes until golden brown and cooked through, then remove and set aside.
Add the remaining sesame oil to the same pan along with the minced garlic, grated ginger, and frozen peas and carrots.
Sauté the vegetables for 3 minutes until tender and fragrant.
Push the vegetable mixture to one side of the pan and crack the egg into the open space, scrambling it until fully set.
Add the cooked brown rice, the cooked chicken, and the coconut aminos into the pan with the vegetables and egg.
Toss all ingredients together for 2-3 minutes over high heat until the rice is slightly crispy and everything is well combined.
Remove from heat, garnish with thinly sliced green onions, and serve immediately.
