ideas, please?

So as you know, my mother in law passed away yesterday.  Services will be thursday night and friday day in central jersey, which is about an hour to an hour and a half from me.  I need some food suggestions!

Here's the deal - we will be going back to my SIL's house after the funeral and interment and will liklely have a bunch of out of town family and local friends joining us.  Elaine will be ordering (ugh deep fried) chicken breasts and bowtie pasta from a local deli that she likes.  Katie will be making her famous "mafia ziti".  I figured I'd make a huge bowl of the strawberry salad we had at the cooking class, but wanted to make a casserole or two.  I'll also be taking some SF desserts to counteract the expected surfeit of creampuffs, napoleons, and other baked goods that this family likes.

Any suggestions for healthy casseroles that can be made ahead (thursday morning, probably), transported easily, reheated... not too carby?  And ideally something that doesn't just "scream" I'm healthy - avoid me...in other words something really YUMMY?  My brain hurts from all the other arrangements and I've come up with zero in the idea range for this part of the program. 

Thanks!
Karen
