Macaroni and Cheese... with beans

This recipe is tweaked just a bit from Jessica Seinfeld's Deceptively Delicious and it is really quite tasty.  I haven't liked quite a few recipes from that cookbook, but every now and then I get that urge to cook a little healthier and I end up trying a few more.  Anyway, the texture is not quite as creamy as your average mac and cheese since it has a bean puree, but it's still yummy (and you can add a bit more milk to make it a touch creamier).

Macaroni and Cheese with White Beans

2 - 2.5 cups spiral pasta
1 cup milk
1/2 cup canned white beans, rinsed and drained (I used Great Northern)
2 cups shredded cheddar cheese
1/2 teaspoon salt
1/8 teaspoon garlic powder
1/8 teaspoon paprika
1/8 teaspoon pepper

Bring large pot of salted water to a boil, add pasta, and cook until al dente.  While pasta is cooking, combine milk and beans in a food processor and process until smooth.
In a large saucepan, over medium heat, cook bean mixture about 1-2 minutes.  Add cheese and cook until melted and creamy, 1-2 minutes longer.  Stir in spices.  Serve warm.
