<p>You’re not a burger connoisseur if you’ve never had an onion burger, and you don’t know onion burgers unless you’ve had one from Tucker’s in Oklahoma City. As the story goes, onion burgers became an iconic Oklahoma food after cafes in the 1920s realized that beef could be stretched further if thinly shredded onions were added to the mix. Today, Tucker’s is serving one of the best renditions of the iconic dish in the entire state. At the top of the menu is the Single Onion Burger with Cheese — the Oklahoma staple topped with your choice of shredded lettuce, tomato, pickles, fresh grilled jalapenos, ketchup, mayo and mustard.</p>
