I did not read all the posts in this thread and the original post was over a year ago. But if the topic morphed into a different direction, well, like I said, I didn't read all the posts.
Our RV menu is absolutely identical to what we eat at home. No changes. The only exception is, the first night of the camping season when we arrive at the campsite, if that be on January 1, or July 1, we always have wine, cheese, and gourmet crackers as a celebration for our first camp of the season year. We set out a candle on the table, turn off all the lights, no electronics, and share a romantic moment. No kids any more makes this a wonderful and delightful tradition for us.
The first morning, after sleeping the first night, of the camping season has always been T-bone steak and eggs for breakfast. We even did this when the kids were little and we tent camped. So, we've been doing this for 37 years. Sometimes the T-bone is cooked over the fire pit, sometimes on a griddle, sometimes on a BBQ. But it's always T-bone and fried eggs. My wife likes them over easy, I like them fried hard. On occasion, for that first breakfast of the season, I've fixed home made hash-browns. But that's an extra, and really not part of the tradition.
Apart form that, every other meal is exactly the same things we eat at home. The only exception is, sometimes is prepared over an open fire and sometimes on an electric skillet or electric flat griddle, in the oven, on the Coleman camp stove, camper stove top or oven, or the microwave. We sometimes bring along an air-fryer too.
Right now we are on a zero Carb, high protein diet, so we are eating a LOT of meats at home. As we are currently (at this very moment) camping in the camper, we are also stocked up on meats. And yes, everything is fresh cooked. No fast food garbage any more.
