Knock off Zupa Wisconsin Cauliflower Soup

9 cups or 8 servings

2 TBS margarine or butter
1 medium onion, chopped
1/4 c all-purpose flour
1/2 t salt
2 c milk
1 can chicken broth
1 head cauliflower cut into small pieces

Optional
1 t Dijon mustard
1 c shredded cheddar cheese

STEP ONE: melt butter over medium heat.  Add onion and cook until golden, about 10 minutes, stirring occasionally
STEP TWO: Stir in flour and salt; stirring frequently for 2 minutes.
STEP THREE: gradually stir in milk, chicken broth and 1.5 cups of water; add cauliflower and heat to boiling over on high heat.
STEP FOUR: simmer for 10+ minutes covered until cauliflower is soft

At this point I cool it off in the fridge over night and freeze for later
