@ana1966 Welcome to Mayo Clinic Connect! As @colleenyoung mentioned, there are several discussions about diet and CKD.
While I agree with your doctor about less protein [make sure what you do eat is quality protein!] and sodium, there is also potassium, calcium, and phosphorous to be mindful of. Eat as few processed foods as you can. Try to stay away from cold cuts and processed meats due to their sodium!
Going to the National Kidney Foundation website, you can find information about healthy diets and meal plans: https://www.kidney.org/nutrition
DaVita Kidney Care is one of the two major players here in the US for dialysis and care. They offer an excellent resource for recipes and tips: https://www.davita.com/diet-nutrition
It's really a challenge to change things around when you have spent many years eating whatever you want. Ask me how I know! And if you are in a multi-person household, you may feel you need to have two separate meal plans. Gently start tweaking things around, don't try to do it all at once. Otherwise, it can be discouraging. Experiment. Get creative with spices. My latest "find" is paprika!
I will be curious to read your discoveries!

There are many books about what to eat and what to avoid or control how much you eat
I suggest you download the Kindle App. and then order sample books to read without commitment and then decide whether to buy.
I suggest you order kindle electronic books which are downloadable as samples to read and review.
