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, and marinate for at least 20 minutes, up to 2 hours for deeper flavor.
02 - Rinse rice under cold water until it runs clear. In a pot, combine rice, water, and salt. Bring to a boil, reduce heat, cover, and simmer 12 to 15 minutes until tender. Let stand covered for 5 minutes before fluffing.
03 - Whisk together mayonnaise, Sriracha or gochujang, lime juice, and honey until smooth. Refrigerate until ready to use.
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 crowding the pan to ensure proper searing.
05 - Fill bowls with warm rice. Arrange steak, shredded carrots, julienned cucumber, chopped kimchi, and greens on top. Drizzle with spicy cream sauce and finish with toasted sesame seeds and sliced green onion.
06 - Serve immediately while the steak is hot and the rice is steaming.
