I am a throw-it-together kind of gal, so I am guessing at the measurements. I made this tonight and it was DELICIOUS! Even the kids were asking for more

1 can chicken broth
16 oz shredded cheese (about 4 cups)
1 cup heavy whipping cream
1/4 cup sour cream
1-2 cups broccoli flowerets

Heat broth and cheese on low heat until cheese is melted. Add heavy cream and sour cream, stirring frequently. Increase heat to medium low, until bubbles begin to form on the top of the soup. Add broccoli flowerets. Cover and simmer 10-15 minutes, or until broccoli is tender. Check frequently to avoid boiling over. Makes about 6 servings.

I don't have the exact carb count on this, sorry. I lost my recipe software when I upgraded to a new computer.
