>>59355253As far back as there are recipes for meatballs, probably since the invention of ground meat. I'm talking dawn of humanity, after neolithic agriculture but the end of the bronze age. Imagine this: you're a young man in bronze age Mesopotamia. Mom comes back from market with a basket full of ground goat meat. She chops some herbs, spices, mixes it, rolls it into meatballs, fries em up in fat. You grab some bread, cut it open, put the meatball in it so you can eat it just as soon as possible. Bam, ancient proto-"hamburger". The history of the hamburger is the history of mankind. Oh, and, honestly, probably pretty good, depending on the meat and spices.
