Prepare the chicken breasts any way you like; I rarely marinate them whole and usually butterfly them for a thiner, more tender piece of chicken with a shorter cooking time. But this marinade will work beautifully either way.
Add the white wine, olive oil, red wine vinegar, lemon juice, crushed garlic, parsley, rosemary, oregano, basil, salt and pepper, and red pepper flakes to a large re-sealable pastic bag or your favourite marinating container (a glass baking dish or a glass bowl works too!). Whisk or shake the marinade ingredients together until they're combined and add the chicken pieces.
Seal the bag well or cover the container or dish and marinate for 1-5 hours in the fridge.
After the chicken pieces have marinated, remove them from the marinade and grill them over medium low heat for about 8-9 minutes per side until they're cooked through completely to an internal temperature of 165 degrees Fahrenheit (75 Celsius). The cooking time will vary depending on the size of the chicken pieces you're using (grill thin pieces for about 6-8 minutes per side).
Serve alongside your favourite salads or summer side dishes for the perfect summer-inspired meal!
