Combine lime juice, lime zest, honey, olive oil, (optional) tequila, garlic, cilantro, and salt and pepper in a bowl and mix well. Reserve ¼ of the marinade in a separate bowl to later drizzle on the chicken.
Add the remaining marinade to a shallow dish or Ziploc bag and add the chicken. Allow to chill in the refrigerator for at least 2 hours, up to overnight.
To grill, preheat your grill to medium high heat. Remove the chicken from the marinade and place chicken on the preheated grill. Depending on the thickness of chicken or temperature of the grill, grill each side of the chicken for about 7-8 minutes, or until cooked through.
Serve warm and drizzle the reserved marinade on the cooked chicken. Garnish with cilantro and lime wedges. Enjoy!
