Slice the pork tenderloin into thin, 1/4-inch thick bite-sized medallions to mimic the texture of pork belly.
In a small mixing bowl, whisk together the gochujang, coconut aminos, sesame oil, rice vinegar, garlic powder, and ginger powder until smooth.
Place the pork slices in a bowl and toss thoroughly with the gochujang marinade until every piece is coated.
In a separate bowl, combine the shredded cabbage with lime juice, salt, and pepper to create a bright, acidic slaw.
Heat a large non-stick skillet over medium-high heat and sear the pork slices for 3 to 4 minutes per side until deeply caramelized and cooked through.
Briefly warm the corn tortillas in a dry pan or over a low gas flame for 30 seconds per side until pliable and toasted.
Assemble the tacos by dividing the glazed pork between the tortillas, topping with the lime slaw, fresh cilantro, and a sprinkle of sesame seeds.
