In a large soup kettle, cook the broccoli, onion, and radishes in the ham broth until mostly tender. Add the mushrooms and green peas, cream cheese, milk, cream, seasonings, and meat of choice.In a small bowl, whisk the xanthan gum and oat fiber together. Add the water and stir to make a paste. Stir into the soup.Simmer for at least 20 minutes, then serve with cheese if desired. Yields about 6 quarts of soup (plenty to feed our family of 6 twice with a little left over).I didn't have very much ham left to put in this soup, so I used a pound of sausage for part of the meat. If you have ham to use up, by all means just use as much as you like of it and omit the sausage.
