I find motorhome recipes hilarious. Just pick up ANY cookbook, or recipe and get to it. MOst fulltimers have figured it out after their first 21 days!
1. Motorhomes are equipped with a complete kitchen.*
2. Motorhomes have running water and electricity.
3. A modern motorhome is better equipped than most unfurnished apartments, or any college dorm.
Essentially, anything that you can cook anywhere in the world, you can prepare in your motorhome.
I migrated from Folding Trailers, (PopUp campers), and their newbees have the same issue, "what to cook"? But then they quickly realize that they also have a virtually complete kitchen and can cook anything.
*Disclaimer: Some late model motorhomes no longer include an oven. However, that is the purchaser's decision to purchase a motorhome without an oven.
