Frankfurter Casserole????

This recipe makes me laugh and raises a question. Is a frankfurter just a hotdog? is it a sausage. I have read a few articles on the subject and I still don't seem to have a clear answer to the question. It really depends on where you live. Or at least that is what I learned from the sausage man.

The encyclopedia Britannica had a more clear definition. https://www.britannica.com/topic/frankfurter
frankfurter, also called wiener or in the United States hot dog, highly seasoned sausage, traditionally of mixed pork and beef. Frankfurters are named for Frankfurt am Main, Germany, the city of their origin, where they were sold and eaten at beer gardens.
Frankfurters were introduced in the United States about 1900 and quickly came to be considered an archetypal American food. The first so-called hot-dog stand, selling the sausages as a sandwich on what was to become the standard long hot-dog bun, was opened at Coney Island, New York, in 1916. The hot dog remained popular in the United States throughout the 20th and early 21st centuries, being especially associated with barbecues, picnics, and athletic events.
The real question is should a frankfurter be in a casserole? I guess we will find out.
