Three-Cheese Spirals

I found this recipe years ago and am now copying it here from our family cookbook binder. Enjoy!

Three-Cheese Spirals 

1 pkg. (16 oz.) spiral pasta                                      

1 egg                                                                      

1 ½ cups (12 oz.) sour cream

1 1/2 cups (12 oz) cottage cheese

1 lb Velveeta cheese, cubed

2 cups (8 oz) shredded cheddar cheese 

Cook pasta according to package directions.  Meanwhile, in a blender, combine the egg, sour cream, and cottage cheese; cover and process until smooth.  Transfer to a large bowl; add process and cheddar cheeses.  Drain the pasta; stir into cheese mixture until evenly coated.  Transfer to a greased, shallow 3 qt. baking dish.  Bake, uncovered at 350 degrees for 15 minutes; stir.  Bake 15-20 minutes longer or until bubbly and edges begin to brown.  Top with a handful of shredded cheese.  If not creamy enough, stir in a little bit of milk.
