Marinate the Beef: In a large bowl, combine all marinade ingredients. Add the thinly sliced beef and toss to coat. Cover and refrigerate for at least 30 minutes, or up to 24 hours for maximum flavor.
Prepare the Kimchi Slaw: In a medium bowl, mix together the chopped kimchi, cabbage, carrots, rice vinegar, sesame oil, and honey. Toss well and set aside to let the flavors meld.
Make the Sriracha Mayo: In a small bowl, whisk together mayonnaise, sriracha, and lime juice until smooth. Refrigerate until ready to use.
Cook the Bulgogi: Heat a grill pan or skillet over high heat. Add the marinated beef in batches, cooking for 2-3 minutes per side until caramelized and cooked through. Remove from heat and set aside.
Warm the Tortillas: Heat tortillas in a dry skillet or directly over a gas flame until warm and slightly charred.
Assemble the Tacos: Place a generous portion of bulgogi beef on each tortilla. Top with kimchi slaw, a drizzle of sriracha mayo, and garnish with cilantro, green onions, sesame seeds, and a squeeze of lime.
