I don't mind some kinds of gluten free pasta, but I found out when I was looking so hard for something palatable (I hate anything with brown rice, the flavor puts me off!) that my wife actually really does not like pasta much at all! So I just gave it up, mostly. The mac and cheese GF version is actually pretty good!

Yes - my mom had a tuna casserole like that too! I think that's really where the basic idea came from.
