Thank you for adding in the line, "And I'm not even making that up." I'm glad that this will be in thousands of papers across the country, with potentially millions of people Googling the phrase, "Dutch Sandwich."
The most likely sandwich would probably be "*hit on a *hingle" where the * represents the letter "S". It is an old military term for the infamous mess hall sandwich "chipped beef on toast" (probably of equal quality to its nickname).
