When I first started reading this thread, I looked to see if my local library had any 'traveling' cookbooks. They had three in the system, for camping and for RVs. So I got them......
......
I don't even cook like that in a house! One of them,
America's Best RV Cookbook, had a 'master supply list' that took up three pages! This included 13 types of chocolate and sweet baking chips and chunks, 8 types of imitation extracts (incl. black walnut, which I've never heard of), 5 kinds of vinegar, canned artichoke hearts and hearts of palm. In my own personal card file, I doubt that I have a single recipe with 15 ingredients.
Of course, this is RV living, which I've never done. But it certainly opened my eyes! You need to be parked in a crowded RV park and hooked up to full utilities just to wash all of the dishes. You need to choose an RV park that has a large grocery store on the other side of the fence. And where do you STORE all of this stuff? And you get to spend half (or more) of every day cooking instead of doing something interesting ...... YIKES!
When I live in a van, it goes more like this:
* Heat water for tea, make tea, add sugar, stir.
* Open can of Raviolios, dump into pot, heat, stir, eat out of pot w/stirring spoon.
* Peel back top of Chips Ahoy cookies (on sale), remove 3 or 4, reseal, eat cookies.
* Maybe make another cup of tea to wash everything down.
* Fill cook pot with water, heat, add a little detergent, wash cup, spoon, pot. Rinse.
