Definition of SANDWICH
a : two or more slices of bread or a split roll having a filling in between
b : one slice of bread covered with food
So a sandwich does not have to be a deli sandwich, or even have two pieces of bread attached. I really don't even think it has to include bread if you dont want! As long as there is an outer layer with some type of filling, i believe THAT is a sandwich. What more can you ask for: carbs, veggies, meat, dairy and even sweets if you desire, in one dish! And I can promise you, I bet you cannot find one person that dislikes sandwiches.
