If you have a little leftover squash from a meal...add it to potato soup. I cook my potatoes with celery and onions in water. Then add milk to the vegetables. Make a rue with milk and flour to thicken the liquids. Add the squash. Cube some ham or fry some bacon. I always add my meats to soups and stews last to keep the meat flavor in the meat. Salt and pepper to taste. Cream cheese can be added if desired or some shredded sharp cheddar.
