I am sure you are looking for free ones, but here is a cookbook by a long time full timer - http://www.amazon.com/Miss-Terrys-Kitchen-Terry-Russell-ebook/dp/B00IP1O66K. 

There must be a gazillion online recipe sites.  If you're using any online recipe sites now, I'd continue with those, as most of the things you can cook in a sticks n bricks you can also cook in an RV.  I often use recipes from the Food Network website, also www.cooks.com.  Often, you can go in to a recipe site & you can enter a search term like "slow cooker" or "convection oven".  You'll get lots of recipes for those specific types of cooking.

My fav is Allrecipes.com!

YEAH for Mike!!

There are a whole lot of delicious recipes online - most of them are NOT healthy and loaded with either fat, sodium, sugar or processed crap (sorry).

Eat clean, simple, local and organic whenever possible. That's my food philosophy and I'm sticking to it on the road or not

As a nutritional consultant and chef, I spend an inordinate amount of time perusing food and recipe related websites. Two of my favorites that have been mentioned here, are EatingWell and AllRecipes. However, many times I have to carefully read through a recipe, look at the nutritional analysis and make various changes based on those numbers. It's my experience that when something is promoted as low fat, you can bet there is more salt and/or sugar. After all, these 3 ingredients are what makes food taste  so yummy, right?

Not saying food has to taste like cardboard - NO WAY! I do believe that MOST things are good in moderation and making healthier choices at least 80% of the time, allows for special occasions, treats and cravings.

Regarding the pantry list on AllRecipes - I think it's a very basic start, BUT, it also suggests canned vegetables (high sodium and low nutrient value), as well as canned fruit (excess sugar). That's not to say that having a couple of cans of beans, corn or peaches on hand are taboo, but fresh is best and then frozen.

It seems that one of the greatest challenges is lack of space (duh), so what's the solution?

I wrote an ebook last year, "How to Stock a Healthy Kitchen Pantry", that I'm in the process of modifying for "off the grid" cooking. I would love input from all of you as to what works and what doesn't work in an RV kitchen; as well as what challenges and successes you have experienced while on the road. Can't live without kitchen tools and ingredients, words of wisdom, shopping, storage, etc.

Would it be helpful to have access to healthier shopping options as  you travel from city to city, state to state?

Thanks for the link Bill. I'll be taking a healthy pastry and baking 1 year program that will cover gluten-free, lactose-free, vegan, diabetic and heart healthy, etc.

I'll be sharing along the way, so stay tuned.

I love discovering new websites and reading articles.

Yeah!! Thanks Sushidog

Along the line of healthier eating, I LOVE http://www.skinnytaste.com.  Of the many recipes of her's I've tried there has only been one I would call a fail.  Even then it wasn't awful.  Just not my favorite.  You can search by ingredient or by type of recipe.   One other advantage for RV cooking -- since portion control is a focus, most things don't make a huge batch!  For things I've tried and like, I often make a double batch to have leftovers.

I'm no cook, and thus have no idea of what makes up a good recipe.  Recently, over on a firearms forum, one of the members started a thread in which he posted pictures and his healthy recipes.  Being as ignorant as I am about cooking, I asked him if any of them were good for those that were diabetics, and, I asked if he could mark future ones as good for diabetics.  I have two sisters-in-law, a brother-in-law, and one son that have diabetes.  He wrote back and listed off the ones that were for diabetics.  Hopefully, his future ones will include that notation with each recipe.
