Dice the chicken breast into small, bite-sized pieces and season with sea salt and black pepper.
Finely mince the garlic and ginger, and thinly slice the green onions, keeping the whites and greens separate.
Heat the sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and sauté for 4-5 minutes until golden brown and cooked through.
Stir in the garlic, ginger, and the white parts of the green onions, cooking for 1 minute until fragrant.
Add the kimchi and gochugaru, sautéing for 2 minutes to caramelize the juices.
Fold in the cooked jasmine rice and tamari, pressing down with a spatula to crisp the bottom of the rice for 3 minutes.
In a separate small non-stick pan, fry the egg until the whites are set but the yolk remains runny.
Plate the fried rice, top with the fried egg, and garnish with the remaining green onion tops.
