I think everyone makes some sort of version of the same food menus they make at home. Just get creative on how to make it easier in an RV.
I know I do. Only after a long day driving the MH RV'ing, I don't like standing over a stove and/or BBQ at a CG cooking each meal and waiting to eat so I designate one day a week at a CG and I cook up a storm of soups, stews, spaghetti, chicken, etc. and put in containers and freeze them. Once I get to the CG and put the levelers down I've got dinner on the table in minutes not hours! :W
This also works well for stopping during the day at rest stops. I don't have to buy and eat junk food, just pop one of my fresh healthy home made meals in the micro.
