In a mixing bowl, combine freshly squeezed lime juice, minced garlic, olive oil, ground cumin, paprika, dried oregano, salt, and pepper. Whisk everything together until well-blended and aromatic.

Cut boneless, skinless chicken breasts into bite-sized pieces. Toss these pieces in the marinade, ensuring each piece is thoroughly coated. Cover and refrigerate for at least one hour.

Once marinated, thread chicken pieces onto skewers. If using wooden skewers, soak them in water for about 30 minutes.

Preheat your grill to medium-high, approximately 400°F (200°C).

Place the skewers on the preheated grill and cook for about 10-12 minutes, turning occasionally until golden brown.

Remove the skewers from the grill and serve with fresh lime or your favorite dipping sauce.
