In a large bag, place your chicken, and add in olive oil, lime juice, garlic, cumin, paprika, chili powder, salt and pepper.
Seal the bag and knead your chicken until its well coated.
Place in the fridge for 30 minutes, up to 3 hours.
When you're ready to cook, remove from marinade and discard marinade.
Grill the chicken, or cook in a saute pan, over medium high heat, until cooked through, or until the chicken reaches an internal temperature of 165 degrees.
Allow the chicken to rest for a few minutes, then chop it up, or shred it.
