Dice the chicken breast into small, bite-sized pieces and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and cook for 5-6 minutes, stirring occasionally, until golden brown and cooked through, then remove and set aside.
In the same pan, add the diced carrots and frozen peas, sautéing for 3-4 minutes until the carrots are tender-crisp.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until the mixture becomes highly fragrant.
Push the vegetables to one side of the pan and crack the egg into the empty space, scrambling it quickly until fully set.
Add the cooked jasmine rice and the cooked chicken back into the pan, then drizzle with the tamari and toasted sesame oil.
Toss all ingredients together over high heat for 2 minutes, allowing the rice to get slightly crispy and well-coated.
Remove from heat and garnish with thinly sliced green onions before serving hot.
