Pat the chicken breast dry and cut into small, bite-sized cubes.
Heat a large non-stick skillet or wok over medium-high heat and add half of the toasted sesame oil.
Season the chicken with sea salt and black pepper, then add to the skillet and sauté until golden brown and cooked through.
Push the chicken to one side of the skillet and add the remaining sesame oil, minced garlic, grated ginger, and frozen peas and carrots.
Sauté the vegetables for 2-3 minutes until they are tender and fragrant.
Add the chilled, cooked jasmine rice to the skillet, using a spatula to break up any large clumps, and stir-fry with the chicken and vegetables for 2 minutes.
Create a small well in the center of the mixture and crack the egg into it, scrambling it quickly until just set before folding it into the rice.
Drizzle the coconut aminos over the entire skillet and toss well to combine all flavors.
Remove from heat and garnish with freshly sliced green onions before serving.
