My three bean salad contains green beans, wax beans, and kidney beans. I have a relative that is not allowed to eat green beans (or any green vegetable) due to health reasons. What can I replace the green beans with? I thought about carrots but I don't think they really belong in this salad. Black beans are too similar to kidney beans. I don't think garbanzo beans, pinto beans, or great northern beans would work. I can't think of any other type of bean. But then, maybe one of the beans I mentioned would work, I don't know. Any suggestions?
