Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
Heat a large non-stick skillet over medium-high heat and cook the chicken until golden and cooked through, then remove and set aside.
In the same skillet, add the toasted sesame oil followed by the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Add the chopped kimchi and sauté for 2 minutes to develop the flavor, then stir in the cooked brown rice.
Press the rice into the pan and let it cook undisturbed for 2-3 minutes to develop a slight crust before tossing.
Return the chicken to the pan and stir in the coconut aminos, mixing well to combine all flavors.
In a separate small non-stick pan, fry the egg to your preference, ideally leaving the yolk runny.
Divide the kimchi rice into a bowl, top with the fried egg, and garnish with sliced green onions.
