Is there a good Mac & Cheese recipe for a lactose intolerant person

Two less traditional options:

http://chefchloe.com/on-the-side/sweet-potato-mac-n-cheese.html
Both of those chefs are well known within the vegan community, and I'm sure both recipes are delicious.

This site has a good vegan mac and cheese: http://www.feastingathome.com/2013/05/vegan-mac-and-cheese.html

Otherwise you could just use lactose free dairy products
