In a mixing bowl, whisk together tequila, lime juice, lime zest, minced garlic, cumin, coriander, oregano, and chili powder.

Place chicken breasts in a large resealable plastic bag and pour the marinade over the chicken. Seal the bag and ensure all pieces are well coated.

Marinate in the refrigerator for at least 30 minutes, or up to 4 hours for deeper flavor.

Preheat your grill to medium-high heat.

Remove chicken from the marinade and season with salt and pepper.

Grill chicken for about 6-7 minutes on each side, or until the internal temperature reaches 165°F and the juices run clear.

Let the chicken rest for 5 minutes before slicing to allow juices to redistribute.

Serve the tequila lime chicken with your choice of sides, such as grilled vegetables or a fresh salad.
