01 - In a bowl, combine soy sauce, brown sugar, sesame oil, rice vinegar, garlic, ginger, black pepper, green onions, and gochujang. Add steak slices, toss to coat evenly, and marinate for at least 20 minutes or up to 2 hours for deeper flavor.
02 - Rinse rice under cold water until the water runs clear. Combine rice, water, and salt in a pot. Bring to a boil, reduce heat to low, cover, and simmer for 12 to 15 minutes until tender. Remove from heat and let stand covered for 5 minutes.
03 - Whisk together mayonnaise, Sriracha or gochujang, lime juice, and honey until smooth and fully incorporated. Refrigerate until ready to serve.
04 - Heat a grill pan or skillet over medium-high heat. Sear steak slices in batches for 1 to 2 minutes per side until just cooked through and caramelized. Avoid overcrowding the pan to ensure proper searing.
05 - Divide warm rice among serving bowls. Arrange steak, shredded carrots, julienned cucumber, chopped kimchi, and greens over the rice. Drizzle with spicy cream sauce and garnish with toasted sesame seeds and sliced green onion.
