Let’s get cooking! Follow these steps to whip up a batch of delicious tacos:

1. Heat the olive oil in a large skillet over medium-high heat. Add the chicken pieces and cook for about 5 minutes, stirring occasionally, until they start to brown.
2. In a small bowl, mix together the chili powder, cumin, smoked paprika, garlic powder, onion powder, cayenne pepper, salt, and pepper. Sprinkle this spice blend over the chicken, stirring to coat evenly.
3. Continue to cook the chicken for another 5-7 minutes, or until it is fully cooked and no longer pink inside. The spices should create a rich, aromatic coating that clings to the chicken pieces.
4. While the chicken is cooking, warm the corn tortillas in a dry skillet over medium heat for about 30 seconds on each side, until they are pliable and slightly charred.
5. To assemble the tacos, place a few pieces of chicken on each tortilla. Top with shredded lettuce, diced tomatoes, chopped cilantro, and crumbled queso fresco.
6. Finish with a squeeze of lime juice over each taco for a fresh, tangy kick.

Remember, cooking is all about adjusting to your taste. Feel free to add more cayenne if you like it spicier or omit it altogether for a milder version.
