Ground beef is simmered in a tangy sauce with onion. My Grandfather owned a drive-in restaurant back in the 1950's. This is his exact recipe for Coney Dogs from back in the day. I make this on special occasions and it is always hit with friends and family. Enjoy.
Sid’s Onion Burger Recipe - For these addictively tasty burgers, ground beef is pressed onto the griddle with paper-thin slices of onion and seared until crisp around the edges. The recipe comes from Sid's Diner, a restaurant in El Reno, Oklahoma, and was featured in Saveur's special Burger issue (August/September 2009).
