Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
Mince the garlic cloves, grate the fresh ginger, and thinly slice the green onions, separating the white parts from the green tops.
Heat the avocado oil in a large non-stick skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through, then remove and set aside.
In the same skillet, add the garlic, ginger, and the white parts of the green onions, sautéing for 1 minute until fragrant.
Add the frozen peas and carrots, cooking for 2-3 minutes until tender.
Push the vegetables to the side of the pan and crack the egg into the center, scrambling it until just set.
Add the chilled jasmine rice and the cooked chicken back into the pan, breaking up any clumps of rice.
Drizzle with tamari and toasted sesame oil, then stir-fry for 3-4 minutes until the rice is heated through and slightly crispy.
Garnish with the green tops of the onions and serve immediately.
