Bolognese sauce can be made so many ways! Make a vegetarian or vegan bolognese by using TVP (textured vegetable protein), veggie (vegan) mince alternative, green lentils (or red lentils or brown lentils) as well as finely chopped walnuts and diced mushrooms. There's a lot to choose from, but we recommend mushroom and lentil bolognese for the best results.
