01 - In a small bowl, combine soy sauce, sesame oil, brown sugar, garlic, ginger, and rice vinegar. Add sliced beef, toss to coat thoroughly, and marinate for at least 15 minutes.
02 - Heat a nonstick skillet over medium-high heat. Add marinated beef and cook for 2-3 minutes until browned and cooked through. Remove from pan and set aside.
03 - In the same pan, quickly sauté the spinach until just wilted, about 1 minute. Remove and set aside.
04 - Blanch bean sprouts in boiling water for 1 minute, then drain well.
05 - In a separate nonstick skillet, fry eggs sunny-side up until whites are set but yolks remain runny.
06 - In a small bowl, whisk together gochujang, honey, water, sesame oil, and rice vinegar until smooth and well combined.
07 - Divide warm rice between two bowls. Arrange beef, spinach, carrot, cucumber, bean sprouts, and green onion in separate sections on top of the rice. Place a fried egg in the center of each bowl.
08 - Drizzle bowls with gochujang sauce and sprinkle with toasted sesame seeds and nori strips if desired. Serve immediately while eggs are warm.
