Potato Cheese Soup

I wish I had a picture of this. It is very easy to make and it is so yummy! It's great for a cold winter night. Serves 8-10.

Ingredients:

3 quarts water
8 potatoes, diced
1 medium onion, chopped
2-3 celery stalks, chopped
2-3 carrots, diced
5 chicken boullion cubes (can add more if would like, I sometimes put 9 if they are small)
salt and pepper to taste

2 cups milk
1 cup flour
3 cups grated cheese

Instructions:

Add potatoes, onion, celery, carrots, chicken boullion, salt and pepper to 3 quarts water. Boil one hour, stirring occasionally. After the soup has boiled for an hour, mix 2 cups milk with 1 cup flour until not lumpy, then add to soup mixture. Cook until soup thickens. Stir in 3 cups grated cheese until melted.
