If you're gonna make Macaroni and Cheese from a box, this is the way to go.  Velveeta Shells and Cheese can be prepared very quickly and has a very creamy taste.  That's because you're actually using the cheese sauce Velveeta is famous for and not that powdered stuff common with other boxes.  You will only need to boil water, put the shells in and cook until tender.  Once you drain the water, squeeze in the cheese and (I recommend) let it set for a few minutes, so the cheese can set.  I also enhance the flavor a bit by adding some sharp cheese.  I can't make enough for my preschooler.  We all love it!
