Your camp meals might be similar to whatever you eat at home but they don't have to be. I find it easier to cook and dehydrate near complete meals this way. Thick soups, stews and sauces. Easy to cook staples such as pasta, rice, beans and pulses fill out the nutritious calories and waistlines. If complete daily nutrition is important to you then you'll soon find protein is the biggest tripping challenge as our Western dietary bias leans towards animal protein of pork, beef, chicken, and fish. The first three are easily dehydrated at home while fish (if you choose not to catch it fresh) is otherwise found in grocery stores in various shelf stable packages. And then there's the vegetable sources of protein, from beans to pulses. I try, and continue to sample, different off the shelf meals. Those an be experiments but be prepared for less taste, more salt, and in the case of complete backcountry fd meals much, much higher prices. You can use them as a starting point I suppose, like a base for expanded recipes of your own. But cooking is not that diffcult to learn (don't tell her I said that), and worth the effort. Good luck with all that.
My wife is a confirmed Vampira carnivore, although she condescends to suffer the indignities of my occasional forays in vegetarian recipes, so I know all about dealing with Mrs Hangry. (lol) We make it work. Fresh ingredients to start the trip, such as eggs for breakfast, steaks/chops for dinners ( night 1 fresh, nights 2&3 from frozen) with veggies. Dry and dehydrated ingredients commence after that. Our meals resemble what we enjoy at home.
