Dice the chicken breast into small, uniform 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 skillet and sear for 4-5 minutes, stirring occasionally, until cooked through and lightly browned.
Stir in the minced garlic, grated ginger, and the white parts of the sliced green onion, sautéing for 1 minute until aromatic.
Add the chopped kimchi to the pan and cook for another 2 minutes, allowing the juices to concentrate and the cabbage to soften.
Incorporate the cooked jasmine rice and coconut aminos, pressing the rice down with a spatula to ensure it makes contact with the hot pan for a slight crisp.
Drizzle the toasted sesame oil over the rice, toss everything together to combine, and remove from heat.
In a separate small non-stick pan, fry the egg over medium heat until the whites are set but the yolk remains runny.
Transfer the fried rice to a bowl, top with the fried egg, and garnish with the remaining green onion tops before serving.
