A lentil burger is a type of vegetarian or vegan burger made primarily from lentils, which are small, round legumes packed with protein and fiber. The lentils are typically cooked and mashed, then combined with various ingredients like vegetables, spices, and breadcrumbs to form a patty. This mixture is then shaped into a burger and can be grilled, baked, or pan-fried. Lentil burgers are often served on a bun with traditional toppings such as lettuce, tomato, and condiments. They are a popular alternative to meat burgers, appealing to those looking for healthier or plant-based meal options.
