Cheese Broccoli Soup

My aunt makes this every year for Christams Eve and Brad loves it.

In large kettle:
6 c. water
1/4 c. chicken bouillon granules (4 Tbsp. or 12 cubes)
1 c. chopped celery
1 large chopped onion (I only do half - enough to make about 1 c. chopped or less)
16 oz. bag frozen chopped broccoli (or three fresh stalks)
1/2 c. margarine

Boil for ten minutes.

Mix separately:
6 c. water
1 1/2 c. flour

Whisk together. Pour into boiling soup, stirring continuously, (and reduce heat to medium-high) while soup thickens.

When thickened, add:

1 large jar Cheez Whiz (will slowly melt as you stir)
Dash of pepper

Keep stirring until chesse melts, then remove from heat. Makes a big pot of soup. Serve hot. Don't add any salt! Serve with fresh cornbread. (We eat it in bread bowls at Christmas.)
