Ingredients:

•  1 lb. pasta (shells or elbows)
• 4 oz. mild cheddar cheese (shredded)
• 4 oz. mozzarella cheese (shredded)
• 4 oz. parmesan cheese (shredded)
•  milk (about an inch in bottom of sauce pan)
• 2 TBS. butter
• salt & pepper to taste
• paprika 
• 2 TBS. cornstartch (w/just enough (very cold) water to create  smooth consistency.)

Directions:

  Cook pasta according to directions on box. Meanwhile cook about an inch of milk (whole milk works best) in saucepan on medium heat with butter, salt & pepper. When butter has almost melted completely, add cheese.  When cheese has melted, reduce heat to low and add corstarch/water mixture to thicken. Combine pasta and cheese sauce.  Put in baking pan.  Top with shredded cheese and paprika.  Broil for about 3 minutes or until cheese browns. 

This is our family favorite.  It's pretty simple and always a hit! Sometimes we add fried, sliced hot dogs into the cheese sauce for a little more flavor.
