We just had the most enormous pot luck, and I am totally stuffed. And I scored the leftover Chinese food, so I will be eating that out of the take-out cartons over the weekend. It gives me such pleasure.
Wraps are not sandwiches. But I'm gonna say that waffles, for example, can be used in place of bread and still make a sandwich. You can make a hot dog sandwich by slicing the hot dogs in half and putting them between slices of bread, but as long as the bun cradles the hot dog it is not a sandwich.
