This was originally from Planter's Walnuts, but I have modified it over the years to suit our tastes. It is a family favorite, requested by my kid's for their birthday dinners and when the older ones come home from college. We eat it hot the first night and then the leftovers cold the next day. Make sure to use only fresh basil - it makes the recipe in my opinion. Be careful as the marinade will flame up on the grill due to the oil content. We usually double this.
