Bean burgers refer to a type of burger made from beans, rather than meat. These patties are typically made from various types of legumes such as black beans, kidney beans or chickpeas that have been mashed and mixed with other ingredients like breadcrumbs, spices, onions, garlic, and vegetable broth to create a texture similar to ground meat. The result is a delicious, protein-packed burger that can be enjoyed by vegans or anyone looking for a plant-based meal option.
