Dice the pork tenderloin and pork belly into small, uniform cubes.
In a small bowl, whisk together the gochujang, tamari, honey, sesame oil, minced garlic, and grated ginger to create the glaze.
Heat a non-stick skillet over medium-high heat and add the pork belly first, rendering the fat until the pieces start to become golden and crispy.
Add the pork tenderloin cubes to the skillet and sear for 4-5 minutes until browned on all sides and cooked through.
Pour the gochujang glaze over the pork and toss continuously for 1-2 minutes until the sauce reduces into a sticky, vibrant coating.
In a separate mixing bowl, combine the shredded cabbage with rice vinegar, lime juice, sea salt, and black pepper, tossing well to create a bright slaw.
Warm the corn tortillas in a dry pan for 30 seconds per side until soft and pliable.
Assemble the tacos by spreading a spoonful of Greek yogurt on each tortilla, topping with the glazed pork, and finishing with a pile of the crunchy cabbage slaw.
