01 - Combine soy sauce, sesame oil, brown sugar, garlic, ginger, and rice vinegar in a small bowl. Add sliced beef and toss to coat. Let 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 - Bring a small saucepan of water to boil. Blanch bean sprouts for 1 minute, then drain well.
05 - In a separate nonstick skillet, fry eggs sunny-side up over medium heat until whites are set but yolks remain runny.
06 - Whisk together gochujang, honey, water, sesame oil, and rice vinegar in a small bowl 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 rice. Place a fried egg in the center of each bowl.
08 - Drizzle with gochujang sauce and sprinkle with toasted sesame seeds. Top with nori strips if desired. Serve immediately while egg is warm.
