Living in New Orleans makes you think anything can be made into a sandwich. After all, if you can have a French fry po’ boy, why not one made of cauliflower? Please note that the cauliflower will be bone dry after it’s roasted, so it will need to be “dressed” in some kind of saucy condiment. In New Orleans, if you order a sandwich “dressed,” that means you want mayo, lettuce and tomato.
