Macaroni and Cheese (with veggies)

* from Jessica Seinfeld's Deceptively Delicious

1 1/2 c elbow macaroni (uncooked)
1 T olive oil
1 T flour
1/2 c nonfat (skim) milk
1/2 c butternut squash or cauliflower puree
1 1/2 c shredded cheddar cheese
4oz reduced fat or nonfat cream cheese
1/2 tsp salt
1/8 tsp paprika
1/8 tsp pepper

Bring a large pot of salted water to a boil, add pasta, and cook according to the directions. Drain.

While the pasta 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 the mixture resembles a thick paste but has not browned, 1-2 min.

Add the milk and cook, stirring every now and then, until the mixture begins to thicken, 3-4 min. Add the vegetable puree, cheddar cheese, cream cheese, and seasoning and stir until the cheese is melted and the sauce is smooth. Stir in the pasta and serve warm.
