In a medium bowl, combine the olive oil, minced garlic, chopped jalapeño, lime juice, lime zest, cumin, paprika, salt, and pepper. Add the chicken breasts and coat them well in the marinade. Cover and refrigerate for at least 30 minutes (or up to 2 hours for more flavor).
Preheat a grill or skillet over medium-high heat. Once hot, add the marinated chicken and cook for about 6-7 minutes on each side, or until fully cooked and the internal temperature reaches 165°F (75°C). Remove from heat and let it rest for 5 minutes.
Once the chicken has rested, use two forks to shred it into bite-sized pieces.
In a dry skillet over medium heat, warm the corn tortillas for about 30 seconds on each side, or until pliable.
Take a warm tortilla and fill it with a generous amount of shredded chicken. Top with shredded lettuce, diced tomatoes, and diced red onions. Finish with crumbled feta cheese and garnish with fresh cilantro leaves.
Place the assembled tacos on a serving platter and serve immediately with lime wedges on the side for extra zing.
Notes
Arrange the tacos on a colorful platter and garnish with lime wedges and additional sprigs of cilantro for a vibrant look. Consider serving with a side of avocado salsa for added flavor!
