Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Season the diced chicken breast with sea salt and black pepper, then add it to the skillet.
Sear the chicken until golden brown and cooked through, approximately 5 to 6 minutes, then remove and set aside.
In the same skillet, add the toasted sesame oil along with the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Add the peas and carrots to the pan and cook for 2 minutes until they are tender and bright.
Push the vegetables to the edge of the skillet and pour the whisked egg into the center, scrambling it until just set.
Incorporate the chilled jasmine rice and the cooked chicken back into the pan, using a spatula to break up any rice clumps.
Drizzle the tamari over the mixture and stir-fry for 3 minutes until the rice is heated through and slightly crispy.
Garnish the dish with thinly sliced green onions and toasted sesame seeds before serving warm.
