Note: many state parks don't allow alcoholic beverages.
At the end of the day, the OP can now see that casseroles, make ahead meals, even freshly assembled meals are all possible at camp.
Most of us go through our favorite dishes and adapt them for the road. The menus we create also reflect the trip's purpose (visiting vs touring vs destination events/competitions etc); locale (including whether or not alcoholic beverages are permitted by the campground); and whether we will have guests or just ourselves to serve.
NYCgrrl: when you make that gumbo I think your campsite will be slammed with drop-in visitors. Better not let Rayusmc know where you are LOL
