Lentils have always been a stand-in for meat since the beginning of veganism. Lentils are hearty and can replace ground beef easily. Lentils come in a variety of colors such as green, red, brown, and black. They cook up quickly, are inexpensive, and a small amount goes a long way. Definite recipes to try are Red Lentil Burgers with Kale Pesto, Lentil Meatballs, Double Decker Lentil Tacos, and South Indian Lentil Stew.
