Macaroni and Cheese

1 1/2 C. Macaroni, cooked
1 Tbsp. Olive Oil
1 Tbsp. Flour
1/2 C. Milk
1/2 C. pureed Butternut Squash or Cauliflower
1 1/2 C. shredded Cheddar Cheese
4 oz. Cream Cheese
1/2 tsp. Salt
1/8 tsp. Paprika
1/8 tsp. Pepper

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