Heat a large skillet over medium-high heat and add half the sesame oil.
Sauté the diced chicken breast until golden and cooked through, then remove and set aside.
In the same pan, add the remaining oil, garlic, and white parts of the scallions, cooking until fragrant.
Stir in the kimchi and gochujang, cooking for 2 minutes to develop a deep, caramelized flavor.
Add the cooked rice and tamari, pressing the rice into the pan to crisp up for 3-4 minutes.
Return the chicken to the pan and toss everything together until well combined.
In a separate small non-stick pan, fry the eggs until the whites are set but the yolks remain runny.
Divide the rice into bowls, top with the fried eggs, and garnish with the green scallion tops.
