In a large skillet, heat the olive oil over medium heat. Add the shredded chicken, chili powder, cumin, garlic powder, onion powder, salt, and black pepper. Stir well to combine and cook for about 5-7 minutes until heated through and slightly crispy.
While the chicken is cooking, warm the corn tortillas in a separate skillet over medium heat for about 30 seconds on each side until pliable.
Once the chicken is ready, assemble the tacos by placing a generous amount of the crispy chicken mixture onto each tortilla.
Top the chicken with shredded lettuce, diced tomatoes, and shredded cheese.
Drizzle sour cream over the top and sprinkle with fresh cilantro.
Serve immediately with lime wedges on the side for squeezing over the tacos.
