In a large skillet, heat the olive oil over medium heat. Add the shredded rotisserie chicken, chili powder, cumin, garlic powder, onion powder, salt, and pepper. Stir to combine and cook for about 5 minutes, until heated through.
While the chicken is heating, warm the tortillas in a separate skillet or microwave until pliable.
To assemble the tacos, place a generous portion of the chicken mixture onto each tortilla.
Top each taco with shredded lettuce, diced tomatoes, and shredded cheese.
Add a dollop of sour cream and sprinkle with fresh cilantro.
Serve with lime wedges on the side for squeezing over the tacos.
