This is a very thick soup, if you want a thinner soup with more liquid add in more water or tomato juice to thin out as desired. I strongly advise to make this soup a day ahead and refrigerate to blend the flavors! You can really use any kind of beans that you desired for this recipe, or use a mixture of canned beans, or use just the kidney beans! Make certain to brown the ground beef very well it adds more flavor to the soup. My recipe for Taco Seasoning Mix #76616 works well for this! Servings is only estimated.
