Pat the chicken breast dry and cut into small, even bite-sized cubes.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Season the chicken cubes with sea salt and black pepper, then add them to the hot pan.
Sear the chicken until it is golden-brown on all sides and cooked through, then remove it from the pan and set aside.
In the same pan, add the diced onion, carrots, and frozen peas, sautéing for 3-4 minutes until the vegetables begin to soften.
Stir in the minced garlic and grated ginger, cooking for just 30 seconds until highly fragrant.
Push the vegetable mixture to the outer edges of the pan and crack the egg into the center, scrambling it quickly until set.
Add the chilled jasmine rice and the cooked chicken back into the skillet, using a spatula to break up any large clumps of rice.
Drizzle the coconut aminos over the mixture and toss everything together for 2-3 minutes until the rice is heated through and slightly crispy.
