Slice the pork tenderloin into small, bite-sized pieces to mimic the texture of pork belly while keeping it lean.
In a small bowl, whisk together the gochujang, tamari, sesame oil, and honey to create the spicy glaze.
Toss the pork pieces in the glaze and let them marinate for at least 10 minutes.
Thinly shred the green cabbage and toss it with rice vinegar, sea salt, and black pepper in a separate bowl to create a quick slaw.
Heat a non-stick skillet over medium-high heat and sear the marinated pork until the edges are caramelized and the meat is cooked through, about 6 to 8 minutes.
Warm the corn tortillas in a dry pan over medium heat until they are soft and pliable.
Assemble the tacos by placing the spicy pork into the tortillas and topping with the cabbage slaw, sliced radishes, and fresh cilantro.
Squeeze the fresh lime over the tacos just before serving for a bright, acidic finish.
