Every May 28, National Hamburger Day celebrates America’s most iconic food. Americans eat over 50 billion burgers a year, so it’s only fitting we set aside a whole day for these special sandwiches. It’s believed that the modern hamburger can be traced all the way back to ancient civilizations such as Egypt. The Egyptians would prepare ground meat that was formed into patties and spiced with various spices.Fast forward to now, where you can get your burger in every meat available — including meatless.Looking to celebrate National Hamburger Day?
