On the topic of food while overlanding. Is it really that critical that you have to pull a kitcken with you? What's wrong with MREs or a camping stove? I do understand having a fridge / cooler. Thinking about it I would much rather have a porta potty than a kitchen with sink.
Eating premade C.R.A.P. (that's an acronym for something) gets old. Breakfast tacos, burritos, skillets, burgers, hand cut fries, grilled pork chops, dutch oven prime rib, carne asada, polo asada, and whatever else I can think of are a hell of a lot better than anything in a bag. But if that's what you like great. My go to day 1 dinner is CFC - Cold Fried Chicken! With some sort of starch like pasta salad or potato salad.
As for a kitchen vs a stove. It is a matter of convenience. The fancier the setup generally the fancier the meals you can prepare. Both work. Being able to prep meals in seconds is nice. Being able to pack up in a matter of minutes is nice too. The only thing critical is the actual camping. How you do it is up to you.
