For a quick, tasty side dish smoked mac and cheese is great! My wife has a great mac and cheese recipe but I decided at the last minute tonight to make some to go with meatloaf so I took the easy way out and threw together a package of Velveeta shells and cheese. After it was done I put it in an aluminum pan, sprinkled some of my home made rub on top and then added another layer of shredded Monterrey Jack cheese and popped it in the CG with two chunks of apple wood and let it cook for about an hour.
It could've went about another half hour to brown up the top layer a bit more but we needed to eat because of plans my daughter had made. If you've never tried smoked mac and cheese I highly recommend it.
