A vegan diet allows for some meat substitutes and processed foods. Most vegans eat soy, so that means that a lot of meat substitutes contain soy and are suitable for a vegan diet. WFPB are recipes that include all plant based foods–no soy, tofu, oils, or artificial meats of any kind. Grilled vegetables on fleek! To clarify, all WFPB eaters are vegan, but not all vegans are eating WFPB.
