My Research Thus Far

The first thing that I learned when beginning my research was that the only fact about sandwiches I had thought was an absolute was not accurate. The first line of Wikipedia proved that all that is required of a sandwich is ONE piece of bread. I had previously thought that a sandwich was really any filling between two pieces of bread. Apparently an open sandwich is one with filling on top of only one piece. Sandwiches have an interesting history, which does in fact involve the ‘Earl of Sandwich’, however, the term is very vague in that it has a massive amount of possibilities. History does not help me very much with my question and a lot of the information is redundant. I have begun looking into people’s basic preferences and through polls and such it appears that the Philadelphia Cheese Steak may come out on top. Ahead, tragically, of even my beloved BLT sandwich. Generally I need to know how to form my argument. Sandwiches are too broad and I really want to make an argument that is not common knowledge. The Philly Cheese Steak is certainly contested, however, and most information I am looking for are in polls. Therefore Encyclopedia Britannica and other sources like it are not  very good for my paper. I am having doubts as to whether this paper will actually be too basic and I am considering switching. Nothing is decided yet though!
