Bean Salad

I make this tasty side sometimes.

1 can organic kidney beans
1 can organic garbanzo beans
1 can italian beans
1 can blue lake beans
1 onion diced
2 celery diced
about 1 cup balsamic vinegrette - Newman's Own is best
Salt to taste (optional)

Drain all beans, rinse kidneys. Dump beans into large bowl. Add onion and celery, pour balsamic vinegrette over. Add salt to taste, if desired. Mix. Chill a few hours in fridge. Stir again before serving.
