Marie Callender's is the best you can buy that are pre-made...and I don't consider them to be that good. I'm making that at home...but, again, not on the summer. I have, but not often, used a pie crust I made...that, in the oven, in Corning Ware.
I'm with you on the casseroles. When Rick mentioned chicken I started thinking about a chicken, broccoli, cheese one...not quite there yet.
