Samosa recipe filing consists of potatoes, paneer and green peas. For vegan version just skip the paneer. I have further enhanced the filling by adding mixed nuts and seeds (cashew, almond, pumpkin seeds and sunflower seeds) for additional crunchiness and increasing the nutritional value. If any family member is allergic to tree nuts or making them for a big get together, then best is to avoid them to be on safe side.
