National Veggie Burger Day is observed worldwide every June 5, celebrating the deliciousness and variety of meatless burgers. Established in 2016 by Amy’s Kitchen, this holiday encourages people to try veggie burgers, which can be made from ingredients like legumes, mushrooms, grains, and tofu. The term "veggie burger" first appeared in print in 1976, but the concept of plant-based patties has roots in various Eurasian cuisines, such as falafel. The Sams brothers, founders of Harmony Foods, introduced the modern veggie burger in 1982, while Paul Wenner developed Gardenburgers around the same time. Celebrations often include trying different veggie burger recipes, dining out for veggie burgers, or hosting cook-offs, with participants encouraged to share their experiences on social media using specific hashtags.
