Heat the avocado oil in a large skillet or wok over medium-high heat.
Season the cubed chicken breast with sea salt and black pepper, then add to the skillet and sear until golden and cooked through.
Push the chicken to the outer edges of the pan and crack the egg into the center, scrambling it quickly until just set.
Stir in the minced garlic, grated ginger, and the frozen peas and carrots, sautéing for 2 minutes until the vegetables are tender.
Add the chilled jasmine rice to the pan, breaking up any clumps with a spatula, and cook for 3-4 minutes until the rice begins to crisp.
Drizzle the tamari and sesame oil over the mixture, tossing everything together to ensure the rice is evenly coated.
Remove from heat and garnish with sliced green onions and sesame seeds before serving.
