Dice the chicken breast into small, uniform bite-sized pieces and season with sea salt and black pepper.
Heat a large non-stick skillet or wok over medium-high heat and add half of the sesame oil.
Add the chicken to the pan and sauté until golden brown and cooked through, then remove and set aside.
In the same pan, whisk the egg and scramble quickly until just set, then remove and set aside with the chicken.
Add the remaining sesame oil to the pan along with minced garlic, grated ginger, and the white parts of the sliced green onions, sautéing for 30 seconds until fragrant.
Toss in the frozen peas and carrots, cooking for 2 minutes until tender.
Increase heat to high and add the chilled jasmine rice, pressing it down into the pan to allow the bottom to get crispy for 2-3 minutes.
Return the chicken and egg to the pan, drizzle with coconut aminos, and toss everything together until well combined and heated through.
Garnish with the green tops of the sliced onions before serving.
