Heat a large skillet or wok over medium heat and add the sesame oil. Swirl to coat the pan.
Toss in the minced garlic and sauté until fragrant, about 30 seconds.
Add the chopped kimchi and cook for a couple of minutes until it starts to soften.
Stir in the drained tuna, breaking it into chunks, and cook for another minute.
Increase the heat to high and add the cooked rice to the pan, stirring to combine everything evenly.
Drizzle in the kimchi juice, soy sauce, and sugar, mixing well. If you're using gochujang for the extra kick of heat, add it now, as well.
Cook for 5-7 minutes, stirring occasionally until everything is heated through and the rice starts to get a little crispy on the edges.
In the meantime, fry the eggs to your liking in a separate pan. If you like your fried rice to have the egg evenly distributed throughout, crack both eggs into a small bowl and break the yolks to mix them together like you’re making an omelet. Then pour it over the eggs about 2 minutes before your kimchi fried rice is cooked to your desired crispiness.
Once the fried rice is done, take the pan off the heat and season with salt and pepper to taste, mixing in the green onions. Serve tuna kimchi fried rice hot, topped with a fried egg, a sprinkle of sesame seeds, and, if you like, some seaweed strips for an added touch of nutrition.
