Rub the pork loin evenly with the chili powder, ground cumin, garlic powder, onion powder, sea salt, and black pepper.
Place the seasoned pork in a small pot with a splash of water, cover, and simmer over low heat until the meat is tender enough to shred.
Remove the pork from the pot and shred it into bite-sized pieces using two forks.
Heat the extra virgin olive oil in a non-stick skillet over medium-high heat.
Add the shredded pork to the skillet in a single layer and press down firmly, searing until the edges become golden and crispy.
Drizzle the lime juice over the crispy pork and toss quickly to combine before removing from the heat.
Warm the corn tortillas in a separate dry pan over medium heat until they are soft and pliable.
Assemble the tacos by dividing the crispy pork between the tortillas and topping with diced red onion, fresh cilantro, and thinly sliced radishes.
