Oh geez I missed this the first time.
You guys don't know what a beefburger is? Loose meat sandwich? Place in Iowa and Nebraska called Maid-Rite that makes them. http://www.google.com/url?sa=t&source=web&cd=1&sqi=2&ved=0CBIQFjAA&url=http%3A%2F%2Fwww.maid-rite.com%2F&rct=j&q=loose%20meat%20sandwich%20diners&ei=S1eFTJmwJ4KKlwemqrCcDg&usg=AFQjCNGlDvtrTN-5_C3laKnwXffodWKm4g&cad=rja The standard is meat, ketchup, mustard, pickles and onions. Freaking heaven. They have a great seasoning that just rocks the meat.
