Black Bean, Corn, and Tomato Salad

I made this for my nephew's First Communion BBQ, and it was a huge hit. I took the recipe straight from the Joy of Cooking; it's fantastically tasty, is great for occasions attended by people who have dietary restrictions, is remarkably easy to make, and travels well. I usually make it the night before to give the flavors a chance to meld in yummy ways.

[Yes, I know I should be posting pics of these creations; I'm working on it!]
