This is my mom's poor man soup. Its easy, hearty, simple, and very cheap to make.... oh and it taste pretty good too. For every 2 potatoes use a 1/4 cup of lentils and 1/4 onion (or more depending on taste) Large dice potatoes, and mince onions and add to heavy bottom pot with lentils. Cover with water and boil with salt, pepper and bay leaf (add water about every ten min. or so) When the potatoes start to fall apart the dish is done. (add more salt and pepper if needed)
