01 - Rinse rice under cold water until clear. In a saucepan, combine rice, water, and salt. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until water is absorbed. Remove from heat and let rest covered for 5 minutes.
02 - In a bowl, whisk together soy sauce, gochujang, brown sugar, sesame oil, rice vinegar, garlic, ginger, honey, and crushed red pepper flakes until smooth.
03 - Toss the sliced beef with cornstarch, then add half of the marinade mixture. Let marinate for 10 minutes while reserving the remaining sauce.
04 - Heat a large skillet or wok over high heat. Stir-fry the marinated beef for 3 to 4 minutes until browned and just cooked through. Add the reserved marinade and cook for an additional 1 to 2 minutes until the sauce slightly thickens.
05 - Fluff the cooked rice and divide among four bowls. Top with the cooked beef, julienned carrot, sliced cucumber, and kimchi.
06 - Sprinkle with sliced scallions, toasted sesame seeds, and nori strips if using. Serve immediately.
