To prepare the marinade, add the olive oil, vinegar, lime juice and zest, oregano, rosemary, garlic, salt, and black pepper to a large bowl and whisk to combine.

Add chicken breasts to a 1-gallon sealable freezer bag and pour marinade mixture over top. Seal bag and turn to coat breasts thoroughly.

Place the bag in the refrigerator to marinate for at least 1 hour to overnight. Turn the bag a couple times to evenly distribute the marinade during this time.

Remove chicken from the refrigerator and discard excess marinade.

Grill the breasts over medium direct heat, turning once, for 10-12 minutes total.

Remove from heat and rest for 5 minutes before serving with your choice of sides
