I want to say, that for some reason guests are not in favor of casseroles. I know I will be going against the grain from many innmates here, but there is something about a casserole that does not seem as B&B friendly. I love them, but hate to have them pared down to meet all the dietary restrictions we have, whereas the casserole ends up being too basic.
It is a comfort food, and therefore a Cracker Barrel favorite I think for many guests. I think they are great, for my own purposes. We also like quiche, in our family and I get in trouble when they say to me "Why don't you make quiche anymore!"
Just like potatoes, everyone loves potatoes and eats them at every diner in the world, but serving it here they are not always #1 for their breakfast choice, which boggles my mind. And I mean all sorts of potato varieties from hashbrowns, homefries, sweet potatoes, fried potatoes, hashes, etc etc
All that to say, do what you want to do, and now I am hungry. For potatoes and a savory casserole (with Frank's redhot on sauce!).
