Something most people do not consider for their summer picnic is to grill an eggplant. Eggplant can be a great vegetable that is easy for a picnic if it is grilled right. The best way to do this is first leave the skin on before cutting so it will keep its shape on the grill. Then use a fork to score the entire eggplant from top to bottom before slicing. This will make the skin become more manageable to eat which will allow people to enjoy the vegetable more.
