Zupa's Wisconsin Cauliflower Soup

This soup is one of Trevor's favorites from the restaurant Zupas. I have never had the soup until I made it at home. It's simple and a great way to use cauliflower. The recipe is adapted from peachtreecooking.blogspot.com.

2 Tbl. butter

1 medium onion, chopped

1/4 cup flour

1/2 tsp. salt

2 cups milk

1 14.05 oz can of chicken broth

1 1/2 cups water

1 head (2.5 lbs) cauliflower, cut into 1 inch pieces

1 tsp. mustard (Dijon or regular)

1 cup shredded cheddar cheese

1 cup pepper jack cheese

bacon bits for garnish

In a 4 quart saucepan, melt butter over medium heat. Add onion and cook until golden, stirring occasionally. Add flour, and salt and cook 2 minutes, stirring frequently. Add milk slowly, then chicken broth, and 1 1/2 cups water. Make sure you continue stirring then add cauliflower and heat to boiling over high heat. Reduce heat to low and cover. Let simmer until cauliflower is tender (about ten minutes). In blender, blend cauliflower until smooth and return to saucepan. Heat until hot, stirring occasionally. Remove from heat and add mustard, and 1 1/2 cups cheese until smooth. Serve with remaining cheese and bacon bits.
