You guys do not know what you are talking about. I'm so tired of these hacks spouting off regarding technical subjects that they clearly have at best, superficial knowledge of. A wrap, for your information, can be composed of hummus, sprouts and tomatoes, or can be something like ham and cheese, or even peanut butter and jelly, rolled right up in a flour tortilla. Overheating is rarely a problem if the right equipment is used, such as a panini press. A six wrap is what you might get for the shop for lunch, depending on how many guys you have, a twelve wrap is more suitable for a multi-family outing.
