Cook the chicken breasts in a pot until fully cooked and tender.

Shred the cooked chicken using two forks.

In a mixing bowl, combine the shredded chicken with chili powder, cumin, garlic powder, onion powder, salt, and black pepper.

Heat the corn tortillas in a skillet or microwave until warm.

Assemble the tacos by placing the chicken mixture on the tortillas.

Top with shredded lettuce, diced tomatoes, shredded cheese, sour cream, and chopped cilantro.

Serve with lime wedges on the side.
