Mac and Cauliflower

I saw cheddar cauliflower at the farmer's market and felt certain that I could get Natty to eat it... Especially when I pureed it and stuck it in some mac and cheese.

Mac and Cauliflower
1/2 box whole wheat elbow macaroni
2 tblsp butter
2 tblsp AP flour
1 1/4 cup whole milk
1 cup shredded cheddar cheese
1 cup pureed cheddar cauliflower (steam then puree in food processor)
Cook macaroni in salted water to desired tenderness. Drain and set aside. Melt butter over medium heat. Add flour to make roux. Cook to a light brown color. Add milk and cook, stirring frequently, until milk thickens. Remove from heat. Add cheese and cauliflower puree. Stir until melted. Add macaroni and combine.
