Begin by rinsing the chicken breasts under cold water and pat them dry with paper towels.

In a large mixing bowl, combine olive oil, lime juice, minced garlic, ground cumin, smoked paprika, and onion powder.

Stir in chopped cilantro and jalapenos until well combined.

Season each chicken breast with salt and pepper.

Place chicken breasts into the marinade and turn to coat well.

Cover the bowl with plastic wrap and refrigerate for at least 2 hours.

Preheat the grill over medium-high heat about 15 minutes before grilling.

Lightly oil the grill grates to prevent sticking.

Grill the chicken for 6-7 minutes on each side or until the internal temperature reaches 165°F (75°C).

Remove the chicken from the grill and let it rest for a few minutes before slicing.

Serve garnished with chopped cilantro and lime wedges.
