In a large skillet, heat the olive oil over medium heat.
Add the shredded chicken to the skillet and sprinkle with chili powder, cumin, garlic powder, onion powder, salt, and pepper.
Stir to coat the chicken evenly with the spices and cook for 5-7 minutes, or until heated through.
While the chicken is cooking, warm the tortillas in a separate skillet or in the oven according to package instructions.
Once the chicken is cooked, remove from heat and set aside.
To assemble the tacos, place a spoonful of the seasoned chicken onto each warmed tortilla.
Top with your desired toppings, such as shredded lettuce, diced tomatoes, sliced avocado, shredded cheese, sour cream, salsa, and a squeeze of lime juice.
Fold the tortillas in half and serve immediately.
Enjoy!
