Healthy Macaroni and Cheese

1 1/2 cups elbow macaroni (I usually use more because this recipe makes a lot of sauce)

Nonstick cooking spray

1 tablespoon olive oil

1 tablespoon all-purpose flour

1/2 cup nonfat milk

1/2 cup cauliflower puree

1 1/2 cups shreaded reduced fat cheddar cheese

4 onces reduced fat cream cheese

1/2 teaspoon salt

1/8 teaspoon paparika

1/8 teaspoon pepper

Cook macaroni. While it is cooking, coat a large saucepan with cooking spray and heat over medium heat. Add the oil, then the flour, and cook, stirring constantly, until mixture resembles a thick paste but has not browned, 1 to 2 minutes. Add milk adn cook, stirring every now and then, until the mixture begins to thicken, 3 to 4 minutes. Add the cauliflower puree, cheese, cream cheese, and seasonings, and stir until cheese is melted and sauce is smooth. Stir in macaroni and serve warm.
