@ldrlw, glad hubby got appropriate care!

Some grocery stores offer unsalted or lightly salted potato chips and in small amounts occasionally are low enough in phosphorus and potassium to be ok on a renal diet.

So Delicious makes dairy free, egg free frozen dessert "ice cream" and the name is accurate! It's great! (In smaller servings than recommended on the label, of course.) So delicious makes a lot of vegan products - cheese, yogurt, etc.

Monk fruit is a Chinese fruit used as a sweetener supposedly ok for kidneys. I don't use it because I rarely eat sugar or sugary foods and as a diabetic I do tolerate well small amounts of maple sugar.

Green salt is a salty-tasting seaweed dried and ground. The company wasn't able to tell me much about its mineral content and people with CKD need to watch intake of minerals like potassium, I decided not to try it. And since I only add a pinch of coarse kosher salt (just a few grains) to something I decided not to experiment with green salt. On average I take in less than 15 mg Na daily. (It took several weeks for me to adjust to not using salt but I no longer miss it.)

Erythritol can cause cramping, bloating and diarrhea if too much is used - different amounts for different people.

One thing which has helped me find vegetarian and vegan foods is online shopping for home delivery (I'm homebound.) I can go to a grocery store's online shopping site (including Walmart) and type vegan in the search box to see what's available and most items have online nutrition labels, ingredients, preparation instructions, etc.

Good luck to you and your husband on your renal diets. Please keep me posted?
