Kidney Bean Salad

I remember my mother going on a quest for this recipe. When my mom had it in her head that she wanted a specific recipe for something or finding out how something was done in a recipe a certain way, there was no holding her back. I think the one thing we could not figure out was whether or not you had to drain the kidney beans. I remember her emailing people and talking to people about finding the "correct" recipe for this... and in my mother's eyes... this is it:

1 can Kidney Beans, drained

1 stem of Celery, chopped fine

2 tsp. finely chopped onion

1 T. sweet relish

1 tsp. vinegar

2 T. Mayo

Mix, refrigerate, serve.
