In a medium bowl, combine gochujang, soy sauce, sesame oil, honey, minced garlic, and grated ginger. Mix well to create a marinade.
Add the chicken thighs to the marinade, ensuring they're well-coated. Marinate for at least 30 minutes (or up to 2 hours in the refrigerator for more flavor).
Preheat a grill or a skillet over medium-high heat. Once hot, add the marinated chicken and cook for about 5-7 minutes on each side, or until fully cooked and the internal temperature reaches 165°F (75°C).
Remove the chicken from the heat and let it rest for a few minutes before slicing it into thin strips.
Warm the tortillas briefly on the grill or in a dry skillet until they are pliable.
Assemble the tacos by laying down some shredded cabbage and carrot on each tortilla, followed by a few slices of the spicy chicken.
Top each taco with fresh cilantro and a sprinkle of sesame seeds.
Serve with lime wedges on the side for squeezing over the tacos just before eating.
