Creating Chicken Tacos with Avocado-Jalapeño Salsa is simple when you follow these steps:

1. Prepare the Chicken: Start by patting the chicken breasts dry with paper towels. This helps to achieve a nice sear.
2. Season the Chicken: In a small bowl, mix the chili powder, cumin, garlic powder, salt, and black pepper. Rub this spice mixture evenly over the chicken breasts.
3. Cook the Chicken: Heat olive oil in a skillet over medium heat. Add the seasoned chicken breasts and cook for 6-7 minutes on each side, or until the internal temperature reaches 165°F (75°C). Remove from heat and let rest for a few minutes.
4. Prepare the Salsa: While the chicken is resting, mash the avocado in a bowl. Add the diced jalapeño, red onion, cilantro, lime juice, salt, and pepper. Stir until well combined. Adjust seasoning to taste.
5. Warm the Tortillas: In a separate skillet, warm the tortillas over low heat for about 30 seconds on each side, or until soft and pliable.
6. Slice the Chicken: Once the chicken has rested, slice it into thin strips.
7. Assemble the Tacos: Place a few slices of chicken in the center of each tortilla. Top with a generous scoop of avocado-jalapeño salsa.
8. Serve Immediately: Enjoy your freshly made tacos while they are warm!
