This person is named Emily Farris. She wrote a casserole cookbook. It comes out next month. The title of the book is Casserole Crazy: Hot Stuff for Your Oven. You should buy the book and then follow the recipes inside the book to make casseroles. I have to admit I've never eaten a casserole, but that's not to say I wouldn't eat a casserole if a casserole were put in front of me.
