01 - Combine soy sauce, sesame oil, brown sugar, garlic, ginger, and rice vinegar in a small bowl. Add sliced beef and toss to coat thoroughly. Let marinate for at least 15 minutes to develop flavors.
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 baby spinach until just wilted, about 1 minute. Remove and set aside.
04 - Bring a small saucepan of water to a boil. Add bean sprouts and blanch for 1 minute, then drain thoroughly.
05 - In a separate nonstick skillet, fry eggs sunny-side up over medium heat until whites are fully 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 onions in separate sections atop the rice. Place a fried egg in the center of each bowl.
08 - Drizzle generously with gochujang sauce and sprinkle with toasted sesame seeds. Add nori strips if desired. Serve immediately while eggs are warm.
