In a large skillet, heat the olive oil over medium heat. Add the shredded rotisserie chicken and stir in the chili powder, cumin, garlic powder, onion powder, salt, and black pepper. Cook for about 5 minutes, stirring occasionally, until heated through.
While the chicken is heating, warm the tortillas in a separate skillet or microwave until soft and pliable.
To assemble the tacos, place a generous portion of the seasoned chicken on each tortilla.
Top with shredded lettuce, diced tomatoes, shredded cheese, and a dollop of sour cream.
Garnish with fresh cilantro and serve with lime wedges on the side.
