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 the water runs clear. Combine rice, water, and salt in a pot. Bring to a boil, reduce heat, cover, and simmer 12 to 15 minutes until tender. Let sit 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 with caramelized edges. Avoid crowding the pan to ensure proper searing.
05 - Divide warm rice among bowls. Arrange seared steak, shredded carrots, julienned cucumber, chopped kimchi, and greens on top. Drizzle with spicy cream sauce and garnish with toasted sesame seeds and sliced green onion.
06 - Serve immediately while the steak is warm and the vegetables are crisp.
