Beef and Cheddar Soup

If you don't like to use leftovers or canned soups then don't look at this recipe, but if you do keep reading.:) I had some leftover roast beef and needed a new way to serve it, so I came up with this. As with all my recipes, you can change the amounts of seasonings according to your own tastes.You can add croutons to the top if you like . :) Submitted on 12/3/10.
