A perfect summer recipe. You can prepare the marinade in the morning and let the breasts marinate up to 8 hours, or just let them sit for 30 minutes before dinner. Instead of chicken breasts, you may also want to try cubes of chicken or pork to make kabobs.
Wash and chop herbs. Put in a food processor or blender with olive oil, lemon juice, garlic, salt, and pepper. Puree until a smooth paste forms. If mixture seems dry and herbs aren't pureeing, add a little more olive oil. Put chicken breasts in a zip-top bag, pour in marinade, seal, and massage briefly. Chill at least 30 minutes (up to 8 hours).
Start your grill and get it hot. Grill chicken 10 to 15 minutes on each side, or until thoroughly cooked through (juices run clear and meat has no pink color). Serve.
