01 - Combine soy sauce, brown sugar, sesame oil, rice vinegar, garlic, ginger, black pepper, green onions, and gochujang in a bowl. Add the thinly sliced steak and toss to coat evenly. Let marinate for at least 20 minutes, or up to 2 hours for deeper flavor penetration.
02 - Rinse rice under cold running water until the water runs clear. Combine rice, water, and a pinch of salt in a pot. Bring to a boil, then reduce heat to low, cover, and simmer for 12 to 15 minutes until tender. Remove from heat and let stand covered for 5 minutes before fluffing.
03 - Whisk together mayonnaise, Sriracha (or gochujang), lime juice, and honey until completely smooth. Transfer to the refrigerator and chill until ready to serve.
04 - Heat a grill pan or skillet over medium-high heat. Sear the marinated steak slices in batches, cooking 1 to 2 minutes per side until just cooked through and nicely caramelized. Avoid overcrowding the pan to ensure proper browning.
05 - Divide warm rice among four bowls. Arrange the seared steak, shredded carrots, julienned cucumber, chopped kimchi, and salad greens on top. Drizzle generously with the spicy cream sauce and finish with toasted sesame seeds and sliced green onion.
06 - Serve the bowls immediately while the steak is hot and the rice is steaming.
